About Converting Millihertz to Microhertz
Millihertz and Microhertz 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 microhertz is 0.000001 hertz units.
Formula
microhertz = millihertz × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 millihertz equals 0.001 base units, and 1 microhertz equals 0.000001 base units, so dividing one by the other gives the direct millihertz-to-microhertz factor of 1000.
Simple example
1 mHz × 1000 = 1,000 uHz
1 millihertz = 1,000 microhertz.
Real-world example
1,000 mHz × 1000 = 1,000,000 uHz
1,000 millihertz = 1,000,000 microhertz.

Reverse conversion: Microhertz to Millihertz
1 uHz × 0.001 = 0.001 mHz
1 microhertz = 0.001 millihertz.
millihertz = microhertz × 0.001

Frequently asked questions
How many microhertz are in 1 millihertz?
1 millihertz equals 1,000 microhertz, using the exact defined conversion factor rather than an estimate.
How do I convert millihertz to microhertz?
Multiply the millihertz value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert microhertz back to millihertz?
Use the reverse factor: 1 microhertz equals 0.001 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 microhertz?
Microhertz (uHz) is a unit of frequency.
Is the millihertz to microhertz conversion exact?
Yes. Both millihertz and microhertz are defined by fixed standards rather than physical artifacts, so the factor of 1000 used above is exact to as many digits as you choose to display.
