Convert frequency units like hertz, kilohertz, megahertz and revolutions per minute.
Frequency measures how many times a periodic event repeats in a unit of time — the standard unit, the hertz, represents one oscillation per second. The hertz was named in honour of German physicist Heinrich Hertz, who in 1887 experimentally proved the existence of electromagnetic waves, confirming Maxwell's theory and paving the way for all the radio, television, and wireless communication technology we know today. Frequency is a quantity that permeates practically all modern technology: the processing frequency of a computer (measured in gigahertz), the frequency of a radio or WiFi wave (measured in megahertz or gigahertz), the frequency of vibration of a guitar string or tuning fork (measured in hertz), and even the frequency of heartbeats (measured in beats per minute, which is technically a frequency unit). This converter calculates between hertz, kilohertz, megahertz, gigahertz, and other frequency units, plus conversions to beats per minute (BPM) and revolutions per minute (RPM), essential for telecommunications engineers designing radio and WiFi systems, audio technicians calibrating sound equipment, musicians and music producers working with audio frequencies, healthcare professionals monitoring heart rate, and any technical context where the periodicity of an event needs to be expressed in different units.
1 Hz equals 60 RPM (revolutions per minute).
1 kilohertz (kHz) equals 1,000 hertz.
Electrical grid frequency (60 Hz in the US), radio frequency, processor speed (GHz), and engine rotation (RPM) are common examples.
