Hertz to millihertz formula
To convert hertz to millihertz, multiply by 1000.
1 Hz = 1000 mHz
Example: 1 hertz = 1000 millihertz
Common frequency conversion mistakes
-
Revolutions per minute convert to hertz by dividing by 60, not by 1000. The prefix step between hertz and kilohertz is 1000, but the step from minute to second is 60, and the two are easy to mix up.
-
Revolutions per second and hertz give the same number but describe different things: rps a rotating object, hertz a periodic signal. Rewriting one as the other never changes the figure.
-
A 50 Hz or 60 Hz supply frequency applies to the voltage, not to motor speed in general. Only synchronous motors follow it exactly. An induction motor runs a few percent below it, which is its whole operating principle.
