Kilohertz to megahertz
Multiply kilohertz by 0.001 to get megahertz.
2,000 kHz = 2 MHz
How to convert kilohertz to megahertz
The megahertz is one million hertz (10⁶ Hz). The kilohertz is one thousand hertz (10³ Hz).
Worked example — 2,000 kHz: 2,000 × 0.001 = 2 MHz.

About kilohertz and megahertz
Kilohertz (kHz)
1 kHz = 0.001 MHzDefinition. One thousand hertz (10³ Hz)
History and origin
The kilohertz is one thousand hertz, a convenient multiple for sound and radio. It became familiar through AM radio tuning and audio sampling.
Current use
Kilohertz are used for audio sample rates and AM radio frequencies.

Megahertz (MHz)
1 MHz = 1,000 kHzDefinition. One million hertz (10⁶ Hz)
History and origin
The megahertz is one million hertz, the scale of radio broadcasting and early computer processors. It marked the clock speed of personal computers into the 1990s.
Current use
Megahertz are used for radio frequencies and were long the unit for processor clock speeds.
