About Converting Millihertz to Kilohertz
Millihertz and Kilohertz both describe how fast something cycles or rotates, and the conversion is a routine part of reading a car tachometer or motor spec sheet against a scientific frequency figure. Specifically: Millihertz is 0.001 hertz units, and kilohertz is 1000 hertz units.
Formula
kilohertz = millihertz × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 millihertz equals 0.001 base units, and 1 kilohertz equals 1000 base units, so dividing one by the other gives the direct millihertz-to-kilohertz factor of 0.000001.
Simple example
1 mHz × 0.000001 = 0.000001 kHz
1 millihertz = 0.000001 kilohertz.
Real-world example
1,000 mHz × 0.000001 = 0.001 kHz
1,000 millihertz = 0.001 kilohertz.

Reverse conversion: Kilohertz to Millihertz
0.000001 kHz × 1000000 = 1 mHz
0.000001 kilohertz = 1 millihertz.
millihertz = kilohertz × 1000000

Frequently asked questions
How many kilohertz are in 1 millihertz?
1 millihertz equals 0.000001 kilohertz, using the exact defined conversion factor rather than an estimate.
How do I convert millihertz to kilohertz?
Multiply the millihertz value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert kilohertz back to millihertz?
Use the reverse factor: 1 kilohertz equals 1,000,000 millihertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a millihertz?
Millihertz (mHz) is a unit of frequency.
What is a kilohertz?
Kilohertz (kHz) is a unit of frequency.
Is the millihertz to kilohertz conversion exact?
Yes. Both millihertz and kilohertz are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 used above is exact to as many digits as you choose to display.
