How to Convert Megahertz to Kilohertz

1 megahertz = 1000 kilohertz

Kilohertz = Megahertz × 1000

Example: 20 MHz × 1000 = 20000 kHz

Reverse Conversion

To convert kilohertz back to megahertz:

  • Remember, 1 kilohertz equals 0.001 megahertz.
  • To convert 20000 kHz to MHz, multiply 20000 x 0.001, resulting in 20 MHz.

20 MHz is also equal to:

About these units

Megahertz: SI decimal multiple of hertz; 1 MHz = 1,000,000 Hz = 10⁶ Hz

Kilohertz: SI decimal multiple of hertz; 1 kHz = 1,000 Hz = 10³ Hz

Frequently Asked Questions

How much is 20 megahertz in kilohertz?

20 megahertz equals 20000 kilohertz. This is calculated by multiplying 20 by the conversion factor 1000.

What does 20 megahertz look like in kilohertz?
