khz to mhz | Exact Decimal + Formula

1 Kilohertz = 0.001 Megahertz

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

About Kilohertz and Megahertz

Kilohertz (kHz)

A kilohertz is 1,000 hertz.

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

Megahertz (MHz)

A megahertz is 1,000,000 hertz.

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

kHz to MHz Formula and Examples

Direct Formula MHz = kHz × 0.001

Inverse Formula kHz = MHz × 1000

Mental Math Shortcut

Divide the value by roughly 1000 to quickly estimate the converted result.

Common Kilohertz to Megahertz Calculations

5 kHz = 0.005 MHz
10 kHz = 0.01 MHz
50 kHz = 0.05 MHz
100 kHz = 0.1 MHz
500 kHz = 0.5 MHz

Precision & Practical Use

For example, 10 kHz = 0.01 MHz — roughly fractional unit measurement.

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 Kilohertz to Megahertz

How many megahertzes are in one kilohertz?

One Kilohertz (kHz) equals 0.001 Megahertz (MHz). To convert kilohertzes to megahertzes, multiply the kilohertz value by 0.001.

How do I convert Kilohertz to Megahertz?

Multiply your kilohertz value by 0.001 to get the result in Megahertz: MHz = kHz × 0.001. For example, 5 kHz = 0.005 MHz.

What is the formula for converting kHz to MHz?

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