# Revolutions per minute to kilohertz

**1 revolution per minute in kilohertz: 1 rpm = 0.00001667 kHz**

kHz = rpm × 0.000016666667

To convert revolutions per minute to kilohertz, multiply by 0.000016666667. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is kHz = rpm × 0.000016666667. Both units measure frequency, so the conversion is a fixed factor that never changes.

## Common questions

### How many kilohertz are in one revolution per minute?

One revolution per minute equals 0.00001667 kilohertz. kHz = rpm × 0.000016666667.

### How do you convert revolutions per minute to kilohertz?

Use kHz = rpm × 0.000016666667. So 10 rpm is 0.0001667 kHz.

### How many revolutions per minute are in one kilohertz?

One kilohertz equals 60,000 revolutions per minute, which is the reverse of the conversion above.
