Convert Megahertz to Hertz (MHz to Hz)
1 megahertz (MHz) = 1000000 hertz (Hz). 1 Hz = 0.000001 MHz. Example: 15 MHz = 15 × 1000000 = 15000000 Hz.

How to Convert Megahertz to Hertz
- 1 MHz = 1000000 Hz
- 1 Hz = 0.000001 MHz
- Example: convert 15 MHz to Hz: 15 MHz = 15 × 1000000 Hz = 15000000 Hz
Formula
Hz = MHz × 1000000
Derivation from SI units:
- 1 MHz = 10⁶ Hz.
- 1 Hz = 1 s⁻¹, one cycle per second.
Both units are defined exactly, so the factor is exact. Megahertz definition: megahertz; Hertz definition: hertz.
Worked examples
- A reading of 88 MHz converts to 88000000 Hz.
88 MHz × 1000000 = 88000000 Hz - A value of 433 MHz is 433000000 Hz.
433 MHz × 1000000 = 433000000 Hz

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