Hertz to kilohertz converter

Convert hertz (Hz) to kilohertz (kHz). Calculate any value, follow the unit-factor steps and check a conversion table.

Updated · How we check
TRY YOUR OWN NUMBER Reverse conversion

Use a decimal point, such as 2.5. Enter a value in Hz; the result is in kHz.

Kilohertz≈ 0.001kHz

Formula

kHz ≈ Hz × 0.001

Worked example

Convert 1 Hz to kHz:

1 Hz ≈ 0.001 kHz

Multiply your Hz value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

Hertz (Hz)Kilohertz (kHz)
0.1≈ 0.0001
0.5≈ 0.0005
1≈ 0.001
2≈ 0.002
5≈ 0.005
10≈ 0.01
25≈ 0.025
50≈ 0.05
100≈ 0.1
1000≈ 1

What hertz measure

Hertz (Hz) represent frequency. One unit equals 10^0 Hz. One hertz represents one cycle per second for a periodic phenomenon.

Reading the result in kilohertz

Kilohertz (kHz) represent frequency. One unit equals 10^3 Hz. One hertz represents one cycle per second for a periodic phenomenon.

Where this conversion helps

Convert the frequency of signals, clocks or oscillations while retaining the same physical cycle rate. Angular frequency uses radians per second and differs by a factor of 2π. Frequency is not data throughput.

How the scale changes

The input unit has a factor of 1e0 Hz; the output unit has a factor of 1e3 Hz. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.

Reading very small or large results

Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
