Frequently asked questions
How many Hz are in one kHz?
1 kHz = 1,000 Hz.
What is the formula to convert kHz to Hz?
Hz = kHz × 1,000. To go back, kHz = Hz × 0.001.
What frequency does a switching power supply run at?
Switching supplies typically run in the tens to hundreds of kHz, which is why their transformers and inductors are small compared with the 50 or 60 Hz equivalent.
