Frequently asked questions
How many kHz are in one Hz?
1 Hz = 0.001 kHz.
What is the formula to convert Hz to kHz?
kHz = Hz × 0.001. To go back, Hz = kHz × 1,000.
Does the mains frequency matter for amps or watts?
For most resistive loads it does not. It matters for motors, transformers and capacitors, whose reactance and speed depend on the frequency, such as 50 Hz or 60 Hz supplies.
