Context values
Some unit families need one extra value for a physically accurate result.
Megahertz is 1000000 hertz units.
Result = input x 1000 / 1e+6.
Frequency uses hertz as the base unit.

About Converting Kilohertz to Megahertz
Kilohertz and Megahertz both describe how fast something cycles or rotates, and the conversion is a routine part of reading a car tachometer or motor spec sheet against a scientific frequency figure. Specifically: Kilohertz is 1000 hertz units, and megahertz is 1000000 hertz units.
Formula
megahertz = kilohertz × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 kilohertz equals 1000 base units, and 1 megahertz equals 1000000 base units, so dividing one by the other gives the direct kilohertz-to-megahertz factor of 0.001.
Simple example
1 kHz × 0.001 = 0.001 MHz
1 kilohertz = 0.001 megahertz.
Real-world example
1,000 kHz × 0.001 = 1 MHz
1,000 kilohertz = 1 megahertz.

Frequently asked questions
How many megahertz are in 1 kilohertz?
1 kilohertz equals 0.001 megahertz, using the exact defined conversion factor rather than an estimate.
How do I convert kilohertz to megahertz?
Multiply the kilohertz value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert megahertz back to kilohertz?
Use the reverse factor: 1 megahertz equals 1,000 kilohertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilohertz?
Kilohertz (kHz) is a unit of frequency.
What is a megahertz?
Megahertz (MHz) is a unit of frequency.
Is the kilohertz to megahertz conversion exact?
Yes. Both kilohertz and megahertz are defined by fixed standards rather than physical artifacts, so the factor of 0.001 used above is exact to as many digits as you choose to display.
