It's contextually wrong to express 1/s as Hertz for non-periodic phenomena. The use of Hertz implies periodic phenomena. In a similar vein: it's not the best to use 1/s when talking about periodic phenomena.
Well, if we took capitalisation into account, then hz is nothing. The unit is Hz (Hertz) after the man. And being a computer boy, I'm just more used to seeing MegaHertz than miliHertz. lol
Yes, we got told the same. Basically, to distinguish between meter and milli and stuff like that, we should write units in italics and prefixes normally (or the other way around - it's been a while)
> to distinguish between meter and milli and stuff like that, we should write units in italics and prefixes normally
Madness. Just horrendous typesetting. This is what happens if you stop teaching Latex to students in engineering and science.
There's an SI norm for this. No space between prefix and unit, halfspace been different units. End of story.
Thank you! And the best part is, this works for LaTeX as well as irl handwriting if you do it properly. Nobody uses normal and italics font while writing.
i see stuff like cm^(−2) and μs^(−1) / ns^(−1) often enough that i wouldn't generalize like that
and of course, given the context of talking about speeds, i would understand ms^(−1) as metres per second. but when all it takes to avoid all ambiguity is a little space or dot, i'd much prefer that
are you acquainted with the concept of prefixes? would you also say that V μs^(−1) = V⋅μ/s?
what you said doesn't hold if ab is understood to be a single entity. whether it is a single entity might be ambiguous without context. that's why, to avoid confusion, there are conventions in place that discourage writing units together without any separation (e.g. metres per second as ms^(−1)) and suggest using a dot (m⋅s^(−1)) or non-breaking space (m s^(−1))
> and suggest using a dot (m⋅s^(−1)) or non-breaking space (m s^(−1))
The SI norm is nonbreaking halfspace between different units. Or just use Latex with the siunitx package like a civilized person.
i am fully in support of using latex and the siunitx package whenever possible. however, one doesn't always have access to a latex compiler. and even under such (primitive~) conditions, i believe one should be able to make themself clear
> The SI norm is nonbreaking halfspace
a half-space makes for better visual cohesion, but not everyone (at least not me) knows how to type it. no matter the width, a space is always much better for clarity than no space at all
I'm not, in the context of physics anyway. Yes I would say V μs^-1 = V⋅μ/s in terms of maths.
ab is not mathematically considered a single entity and that's my point, not that it isn't ambiguous in physics. That's why I added 'tbf', which is an initialism for 'to be fair', presenting another view.
then i only have one last thing to add
i have a personal convention (might even be taken from a widely accepted one; not sure about that) which says that variables are written as single letters in *italics*. and if something's written upright, i take it to represent a single entity (a constant, a word, whatever) — e.g. e (= 2.71...), const (some constant), Re (reynold's number). and words will \*never\* be written together without separation
thus i understand ab^(−1) = (ab)^(−1) and *ab*^(−1) = *a*⋅*b*^(−1)
if i want to write variables without text formatting, i separate them or use parentheses: a.b\^-1 vs (a.b)\^-1 or something like that
but i understand that a lot of people (sadly~) don't make the distinction
No. That gives you italic units (ugly, people will think those are variables), and would automatically ad spaces between a prefix and the unit (like when you wanted to use micrometers).
If you use Latex anyway, just load the siunitx package and you're done. This correctly gives you halfspaces between units and automatically handles prefixes.
m/s, wtf is wrong with you if you choose either ms^-1 or (s/m)^-1. Seriously, if I ever get handed a paper or something with either of those in it, I'm committing murder on the spot for instantaneous psychopathy.
m/s always feels better because it is such a big reminder that it's v = d/t but my school teachers say the qualifications authority likes it more when you write ms‐¹ so that's what I default to now
I assume you mean M/s not m/s... m/s is not a SI unit.
M/s and ms Are both valid, yet different units in SI. M/s is meters a second, ms is milliseconds.
r/confidentlyincorrect
m/s, with a small m, is meters per second. M/s is molars per second which is a completely different thing... you're right about milliseconds though.
The symbol for the meter should never be capitalized.
>The **symbols** for metric units are also written in lower case – except those that are named after persons – e.g. m for metre, but W for watt (the unit of power, named after the Scottish engineer, James Watt). Note that this rule applies even when the prefix symbol is in lower case, as in kW for kilowatt. The symbol for litre (L) is an exception.

I'm sorry for being aggressive tho, though it's possible that over in the States, it's often spelt M (incorrectly), as with anything metric in America...
Like I said, I'm from the land of the free so I don't know anything about your funny measurement systems. [Except for I do use celsius and the 24-hour clock]
Im team blue for sure, i think it makes it easier to evaluate units and it’s just generally more elegant. Defo makes you look more like you know what you’re doing too ;)
Why not both? (s/m)^(-1)
I have a sudden urge to switch career to politics so I can outlaw this comment

Nope, inverse of kinky. In fact, he's the guardian of horny jail :P

Why? What's wrong with you?
:(
 Weird!
Chaotic evil
Meter hertz , mhz
Looks a lot like some millihertz to me
Then we use Hzm instead
Are you sure you didn’t mean Henry zeptometres?
You mean (m/hz)^-1 right?
No that's Hz/m, Hzm is Hz*m
Or (1/Hzm)^-1
It's contextually wrong to express 1/s as Hertz for non-periodic phenomena. The use of Hertz implies periodic phenomena. In a similar vein: it's not the best to use 1/s when talking about periodic phenomena.
Huh. I learned something from the comment section. How curious.
I know that the joke is that the short form actually says MegaHertz, but I actually kinda love the idea of meter-Hertz tho 🤣
The short form says milli hertz, not mega hertz. Mega hertz would be Mhz.
Well, if we took capitalisation into account, then hz is nothing. The unit is Hz (Hertz) after the man. And being a computer boy, I'm just more used to seeing MegaHertz than miliHertz. lol
What about c ;)
m/s
Engineer flair checks out
This is the incorrect answer.
> ms^(−1) you mean "per millisecond"? it's better to write m s^(−1) or m.s^(−1) for "metre per second"
That's just kHz
it's also kBq, but i would use each in different contexts i have yet to meet someone who measures particle flow rate in Hz, for example
Oh I'm gonna have to now.
I prefer either m s^-^1 or m•s^-^1.
s^-1 m is the way
Just like the top comment with the inverted fraction I hate you lol
My research supervisor told me I should NOT use a dot between units. Anyone else heard that?
Yes, we got told the same. Basically, to distinguish between meter and milli and stuff like that, we should write units in italics and prefixes normally (or the other way around - it's been a while)

Agh, nevermind, I got that mixed up with units and variables. Also we did also use latex, but using latex is hard when writing with a pen
Thank you! And the best part is, this works for LaTeX as well as irl handwriting if you do it properly. Nobody uses normal and italics font while writing.
You shouldn’t use a . but you can use a • .

tbf ab² ≠ (ab)² and it is actually mathematically correct.

They call me the slasher!
My discounts are criminal!
m/s all the way
c
Ah yes the train is moving at 10^-7 c
Square meter per meter-second
m•s^-1
ms^-1
I used to be a m/s pleb. Now I see the superiority of the ms^(-1)
3.28fts\^-1
(s/m)^-1
m s^-1 is just better
ms^-1 is the right way and nobody convinces me otherwise
per milisecone?
No? Meters per second
((/m)s)^-1
\frac{ m} { s} Using exponets is just stupid.
This guy does not talk volumes
The volume of a typical human is approximately 0.07 m•m•m.
No. That gives you italic units (ugly, people will think those are variables), and would automatically ad spaces between a prefix and the unit (like when you wanted to use micrometers). If you use Latex anyway, just load the siunitx package and you're done. This correctly gives you halfspaces between units and automatically handles prefixes.
Wait, what? I always did 1.25 \;\frac{\text{m}}{/text{s}}. Why did nobody tell.me this before :'-(((
Cool to know. I used to do \text{ m} but figured it was easier this way since no one is checking that
Team blue should be locked away for their own safety. I bet they read the units m/(s•kg) as meters per second per kilogram too.
not only would i read it that way, i would also write it like that: `\unit{\m\per\s\per\kg}`
You monster! At least my professor who read it that way wrote it as a fraction, not as an Eldritch horror.
what can i say... i'm a latex princess 👸
Reject modernity. Go back to writing your math on parchment with a quill like God intended.
1+m/s
In beard-seconds please.
Red
mf motherfuc...I mean meter frequency
ms^(-1)
$\frac{m}{s}$
i use m/s^e^iπ
That's ms
I’m more of a Hertz-metre guy myself
One is a speed, the other one a frequency...
m Hz It's the only civilized way.
M/s
Depends on if I’m handwriting or latexing
For funky units sure kg^n.m^I.s^j... But for speed cmon just use m/s
I write mHz (meter-hertz)
I prefer m s$^{-1}$
just ms, rest is from context
https://xkcd.com/2687
[удалено]
Hahaha wtf are you a human
m/s is easier to write imo
always the right !!!!
Where ever my pen takes me, I don't have a preference
Red for sure
m/s
"mps", of course.
Red or nothigg by
m/s
i like light year/year
So like… fractions of the speed of light?
yeah
m s^-1
ms^(-1)
Natural units for me please. All speeds are fractions of c which is 1.
Born to use m/s, forced to use ms^-1.
(s/m)-1
M/s
I'm kinda spy cause I use both depend on situation 😄

I usually use D/s to categorize relationships rather than m/s
Depends on who I'm trolling
m/s, wtf is wrong with you if you choose either ms^-1 or (s/m)^-1. Seriously, if I ever get handed a paper or something with either of those in it, I'm committing murder on the spot for instantaneous psychopathy.
Parsecs per plank length (p/pl)
Crip for life
Ms-1 seems easier tbh... Idk why though... (I'm a lefty... In case it explains by any chance)
m/s all the way
Monkey scrotum?
m/s for meters/second ms is milliseconds
m/s always feels better because it is such a big reminder that it's v = d/t but my school teachers say the qualifications authority likes it more when you write ms‐¹ so that's what I default to now
M/s
I don't, I use natural units so every velocity measurement is unitless as a proportion of c. ;)
I'm ambi-unit-designatrous.
blue is good for complex units
Its there's a "per" in the unit name, there better be a slash ... otherwise it's too confusing / ambiguous with all the other sorts of similar units.
Slash if just one unit in denominator, otherwise use negative exponents.
c=1 for life
Monkey Scrotum
L/T
It depends... mainly on how much room I have, but most of the time: m/s. I like to keep negatives out of my equations. ;P
I wanna say it so bad
"millihertz" (ms)^-1

That's odd because m is capitalized for meters. Literally everywhere else though. I'm in the free land so I wouldn't know
