- 1 kHz = 60000 rpm
- 1 × 60000 = 60000 rpm
How to convert kilohertz to revolutions per minute
1 kHz = 60,000 rpm, so multiply by 60,000 to go from kilohertz to revolutions per minute. Going the other way, 1 rpm = 1.66666666667 × 10⁻⁵ kHz.
rpm = kHz × 60,000 kHz = rpm × 1.66666666667
Worked example:
1 kHz = 60000 rpm 5 × 60000 = 300000 rpm
