Convert Terahertz to Megahertz (THz to MHz)
1 terahertz (THz) = 1000000 megahertz (MHz). 1 MHz = 0.000001 THz. Example: 15 THz = 15 × 1000000 = 15000000 MHz.

How to Convert Terahertz to Megahertz
- 1 THz = 1000000 MHz
- 1 MHz = 0.000001 THz
- Example: convert 15 THz to MHz: 15 THz = 15 × 1000000 MHz = 15000000 MHz
Formula
MHz = THz × 1000000
Derivation from SI units:
- 1 THz = 10¹² Hz.
- 1 MHz = 10⁶ Hz.
- 1 THz = 1000000000000 Hz ÷ 1000000 Hz per MHz = 1000000 MHz
Both units are defined exactly, so the factor is exact. Terahertz definition: terahertz; Megahertz definition: megahertz.
Worked examples
- A reading of 1 THz converts to 1000000 MHz.
1 THz × 1000000 = 1000000 MHz - A value of 193.4 THz is 193400000 MHz.
193.4 THz × 1000000 = 193400000 MHz

Where it's used
Terahertz are used for optical communications, while megahertz appear in FM radio and TV. Both measure frequency and rotational speed, so the conversion is a fixed factor.
