How do I convert megahertz to kilohertz?

Multiply the megahertz value by 1000. So x MHz × 1000 = the equivalent in kHz.

What is 5 megahertz in kilohertz?

5 megahertz equals 5000 kilohertz.

What is 10 megahertz in kilohertz?

10 megahertz equals 10000 kilohertz.

What is 100 megahertz in kilohertz?

100 megahertz equals 100000 kilohertz.

How do I convert back from kilohertz to megahertz?

Multiply the kilohertz value by 0.001. For example, 1 kHz = 0.001 MHz.

Is the megahertz bigger than the kilohertz?

Yes. 1 megahertz is larger than 1 kilohertz — specifically 1000 times larger.

Are these conversion factors exact?

The factor is derived directly from the SI definitions of megahertz and kilohertz; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.

Megahertz to Kilohertz Converter

1 MHz = 1000 kHz (megahertz → kilohertz)

1 MHz = 1000 kHz

1 megahertz equals 1000 kilohertz. To convert megahertz to kilohertz, multiply the megahertz value by 1000. For quick reference: 1 MHz = 1000 kHz, 5 MHz = 5000 kHz, 10 MHz = 10000 kHz, 100 MHz = 100000 kHz.

Real-world reference

FM radio stations broadcast in the range of 88–108 MHz. Early home computers ran at processor speeds of a few MHz. In kilohertz, that gives you: 1 MHz = 1000 kHz, 10 MHz = 10000 kHz, 100 MHz = 100000 kHz.
