Convert Hertz to Megahertz (Hz to MHz)
1 hertz (Hz) = 0.000001 megahertz (MHz). 1 MHz = 1000000 Hz. Example: 15 Hz = 15 × 0.000001 = 0.000015 MHz.

How to Convert Hertz to Megahertz
- 1 Hz = 0.000001 MHz
- 1 MHz = 1000000 Hz
- Example: convert 15 Hz to MHz: 15 Hz = 15 × 0.000001 MHz = 0.000015 MHz
Formula
MHz = Hz ÷ 1000000
Derivation from SI units:
- 1 Hz = 1 s⁻¹, one cycle per second.
- 1 MHz = 10⁶ Hz.
Both units are defined exactly, so the factor is exact. Hertz definition: hertz; Megahertz definition: megahertz.
Worked examples
- A reading of 50 Hz converts to 0.00005 MHz.
50 Hz × 0.000001 = 0.00005 MHz - A value of 440 Hz is 0.00044 MHz.
440 Hz × 0.000001 = 0.00044 MHz

Where it's used
Hertz are used for mains power (50/60 Hz), while megahertz appear in FM radio and TV. Both measure frequency and rotational speed, so the conversion is a fixed factor.

Frequently asked questions
How many megahertz are in 1 hertz?
1 Hz = 0.000001 MHz.
How do I convert hertz to megahertz?
Multiply the value in Hz by 0.000001, or divide it by 1000000. For example, 15 Hz × 0.000001 = 0.000015 MHz.
Is the Hz to MHz conversion exact?
Yes. Both units are defined exactly, and 1 Hz is exactly 0.000001 MHz.
