How to use this converter
Choose your starting and destination units, then enter a value. Results update as you type. You can swap the direction and choose the displayed precision.
Example: Hertz to Kilohertz
value × 0.001 = result
Here the starting unit is Hertz (Hz) and the result is in Kilohertz (kHz). This category includes reciprocal relationships. Use a positive input and check the selected direction.
Worked examples
- 1 Hz ≈ 0.001 kHz
- 10 Hz ≈ 0.01 kHz
- 100 Hz ≈ 0.1 kHz
Available frequency wavelength options
Hertz (Hz) · Kilohertz (kHz) · Megahertz (MHz) · Gigahertz (GHz) · Terahertz (THz) · Wavelength in meters (m) · Wavelength in centimeters (cm) · Wavelength in nanometers (nm)
Unit conventions
Electromagnetic waves in vacuum: frequency × wavelength = 299,792,458 m/s. Other media require their propagation speed.
Frequently asked questions
Why can displayed results differ slightly?
Numeric results are rounded for display. Increase the precision setting to see more digits. Different unit conventions can also produce different results; check the complete unit label.
Can I convert in the opposite direction?
Use the swap control to reverse the selected units or bases.
