Frequently asked questions
What is the source unit in this conversion?
The source unit is the hertz (Hz). The hertz is one cycle per second.
What is the destination unit in this conversion?
The destination unit is the millihertz (mHz). Millihertz is 0.001 hertz units.
How do I convert hertz to millihertz?
Multiply the hertz value by 1000. For example, 10 Hz × 1000 = 10000 mHz.
Is the hertz to millihertz conversion exact?
Yes. The relationship between these units is a fixed mathematical or SI-defined ratio, so the conversion factor is exact rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in hertz needs to be compared with, or reported in, millihertz, such as in engineering, scientific, or everyday calculations.
Can I convert millihertz back to hertz?
Yes. Multiply the millihertz value by 0.001 to get hertz.

About this conversion
This page converts hertz (Hz) to millihertz (mHz) within the frequency converter.
The hertz is one cycle per second. Millihertz is 0.001 hertz units.
The formula is millihertz = hertz × 1000, based on each unit's fixed relationship to the frequency converter's base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
