mhz to khz | Exact Decimal + Formula

1 Megahertz = 1000 Kilohertz

One megahertz equals exactly a thousand kilohertz. Real-world use: fm radio, computer bus speeds, and older processor clocks. This page expresses those values in kilohertz, which is used for am radio bands and ultrasonic applications. Type a value above for an instant answer; the exact formula and the reference table are below.

About Megahertz and Kilohertz

Megahertz (MHz)

A megahertz is 1,000,000 hertz.

Where it's used: FM radio, computer bus speeds, and older processor clocks.

Kilohertz (kHz)

A kilohertz is 1,000 hertz.

Where it's used: AM radio bands and ultrasonic applications.

MHz to kHz Formula and Examples

Direct Formula kHz = MHz × 1000

Inverse Formula MHz = kHz × 0.001

Mental Math Shortcut

Multiply the value by roughly 1000 to calculate the equivalent amount in your head.

Common Megahertz to Kilohertz Calculations

5 MHz = 5000 kHz
10 MHz = 10000 kHz
50 MHz = 50000 kHz
100 MHz = 100000 kHz
500 MHz = 500000 kHz

Precision & Practical Use

For example, 10 MHz = 10000 kHz — roughly multiple unit increments.

Results are computed to up to 9 decimal places. Round to the precision of your measuring instrument — for most frequency applications, 2–3 significant figures are plenty.

How to Convert Megahertz to Kilohertz

How many kilohertzes are in one megahertz?

One Megahertz (MHz) equals 1000 Kilohertz (kHz). To convert megahertzes to kilohertzes, multiply the megahertz value by 1000.

How do I convert Megahertz to Kilohertz?

Multiply your megahertz value by 1000 to get the result in Kilohertz: kHz = MHz × 1000. For example, 5 MHz = 5000 kHz.

What is the formula for converting MHz to kHz?

The conversion formula is kHz = MHz × 1000. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
