Kilohertz to Megahertz formula
Converting kilohertz to megahertz is a single multiplication by 0.001.
MHz = kHz × 0.001
Put another way, one kilohertz is exactly 1/1,000 of a megahertz.
Why this factor: the kilohertz and the megahertz are both defined against the hertz, so dividing one definition by the other gives 0.001 directly. Both definitions are set out in full below.
To go the other way, divide by 0.001 — or use the Megahertz to Kilohertz converter, which is the same calculation reversed.
Worked example
Given 1000 kHz, multiplying by 0.001 yields 1 MHz.
1000 kHz × 0.001 = 1 MHz
The converter above does this for any value you type, in either direction.
What is a kilohertz?
A kilohertz is 1,000 cycles per second.
Definition: Exactly 1,000 hertz.
Where it is used: AM radio frequencies, audio sample rates (44.1 kHz for CD audio), and ultrasonic ranges.
What is a megahertz?
A megahertz is one million cycles per second.
Definition: Exactly 1×10⁶ hertz.
Where it is used: FM radio and broadcast bands, memory clock speeds, and radio communications.
Kilohertz vs Megahertz
The kilohertz and the megahertz belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
