Convert between frequency units and view electromagnetic wavelength
This frequency converter supports seven units: Hertz (Hz), Kilohertz (kHz), Megahertz (MHz), Gigahertz (GHz), Revolutions per Minute (RPM), Radians per second (rad/s), and Degrees per second (°/s). When a frequency in the radio or light spectrum range is entered, the tool also calculates the corresponding electromagnetic wavelength using λ = c / f, where c = 299,792,458 m/s.
Select the frequency unit you want to convert from, enter the value, and click "Convert". All equivalent frequencies are displayed. If the resulting frequency falls within the electromagnetic spectrum (below about 10¹⁵ Hz), the corresponding wavelength is shown in meters, centimeters, or nanometers as appropriate.
Divide RPM by 60 to get Hertz. Since 1 RPM equals 1/60 Hz, a motor spinning at 3600 RPM operates at 60 Hz. This is commonly used for rotational machinery, engines, and electrical generator synchronization.
Frequency (f) and wavelength (λ) are inversely proportional: λ = c / f, where c is the speed of light (299,792,458 m/s). Higher frequencies have shorter wavelengths. For example, 100 MHz has a wavelength of about 3 meters, while 1 GHz has a wavelength of about 30 cm.
