Frequently asked questions
What is the source unit in this conversion?
The source unit is the kilohertz (kHz). Kilohertz is 1000 hertz units.
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 kilohertz to millihertz?
Multiply the kilohertz value by 1.000000e+06. For example, 10 kHz × 1.000000e+06 = 1.000000e+07 mHz.
Is the kilohertz 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 kilohertz needs to be compared with, or reported in, millihertz, such as in engineering, scientific, or everyday calculations.
Can I convert millihertz back to kilohertz?
Yes. Multiply the millihertz value by 0.000001 to get kilohertz.

About this conversion
This page converts kilohertz (kHz) to millihertz (mHz) within the frequency converter.
Kilohertz is 1000 hertz units. Millihertz is 0.001 hertz units.
The formula is millihertz = kilohertz × 1.000000e+06, 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.
Use the calculator above for instant results, or the table below for common kilohertz values already converted to millihertz.
