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.
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.
