How to Convert Manually
Use these steps to convert Megahertz values to Kilohertz without the calculator.
- Write down the value in Megahertz (MHz) that you want to convert.
- Multiply that value by 1000.
- For example, 10 Megahertz × 1000 = 10000 Kilohertz.
- Label the result as Kilohertz (kHz).

About Megahertz and Kilohertz
The megahertz is one million hertz. FM radio (87.5–108 MHz), older CPU clocks, and RAM speeds are quoted in megahertz. The kilohertz is 1,000 hertz. AM radio frequencies, audio sample rates (44.1 kHz), and ultrasound run in the kilohertz range. One Megahertz equals 1000 Kilohertz (1 MHz = 1000 kHz). Megahertz is used in FM radio frequencies and in RAM and bus speeds. Kilohertz is used in AM radio tuning.
Precision and Rounding:Frequency conversions are exact decimal shifts except rpm and rps, which involve the factor 60. Audio and radio work round to convenient figures; clock signals, tuning, and rotating machinery balancing need the unrounded value.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
