By convention, compound SI units (e.g. N•m) are separated by a space or multiplication dot and are not just smashed together. The lack of such a separator in the above example implies the “milli” prefix.
No one uses millihertz and neither meterhertz. If you want to do it correctly the first one would be acceptable for milli as scale. The second one would need to be written as m • Hz.
All metric unit prefixes are possible. Like femtohertz, picohertz, centihertz, decihertz, decahertz, hectohertz, petahertz, zettahertz. Not sure if they are used often.
Well Hz is a frequency per second. It doesn’t make much sense to use them for low frequency things but it’s still possible. Just most things that happen less than once per second are usually described in units like seconds, hours and more.
I think there’s something like 43/500ths of a Bigole Hertz to a regular Hertz; but that’s if you’re using English Bigoles. I think it’s 43.9/500ths for a US Bigole.
I have no idea if this is meterhertz or millihertz
yes
nHz is Nanohertz 1/1,000,000,000 Hz (Billionth)
µHz is Microhertz 1/1,000,000 Hz (Millionth)
mHZ is Millihertz 1/1,000 Hz (Thousandth)
Hz is Hertz 1 Hz (Base Unit, one per second)
kHz is Kilohertz 1,000 Hz (Thousand)
MHz is Megahertz 1,000,000 Hz (Million)
GHz is Gigahertz 1,000,000,000 Hz (Billion)
THz is Terahertz 1,000,000,000,000 Hz (Trillion)
I suppose there are probably more that I’m not aware of, but I hope this clears it up.
No, that absolutely does not resolve the confusion between meter (m) and milli (m)
I feel like a dumbass
I totally read your comment as “Megahertz or Millihertz”
Now I realize it should just be Meters•Herts or m•Hz
Standing alone ‘m’ is metre.
With a decimal modifier ahead of it, ‘m’ is metre
Immediately before a symbol it is milli (one thousandth)
mm - the first m is before the metre symbol, it is the milli multiplier, the second m is after a multiplier, so it is the symbol for metre
mHz - the m is before the symbol Hz (for Hertz) so it is the milli multiplier
km - the m is after the K (kilo, thousand times) multiplier, so it is metre
You probably spell metre ‘meter’, but a meter is a whole different word in English

m • Hz.Millihertz are used for gravitational waves in Astrophysics.
Pretty sure kilo is lowercase, actually.
Son of a bitch, you’re right lmao
Big K is Kelvins for temperature
Kelvinhertz
Sufficient Kelvins do hurt, I guess

Can Hertz be imperial or are they strictly metric?

I usually just rent from Enterprise. They pick you up!
I’m American and I’ve never seen any other unit used for frequency unless you count adjectives like “daily”.
RPM (revolutions per minute) is an old rotational measure
But the second is the same in both systems so I wouldn’t be surprised if America called revs per second “Hertz”
