What is a Frequency Converter?
A Frequency Converter is a free online tool that converts frequency values between hertz (Hz), kilohertz (kHz), megahertz (MHz), and gigahertz (GHz). It is useful for electronics, radio communications, audio engineering, and physics applications.
How to calculate frequency conversion manually (the formula)
Frequency conversion uses powers of 1,000. To convert Hz to kHz, divide by 1,000. To convert kHz to MHz, divide by 1,000. To convert MHz to GHz, divide by 1,000. Going in reverse, multiply by 1,000 for each step.
Example calculation
Convert 2,500 Hz to kHz: 2,500 ÷ 1,000 = 2.5 kHz. Convert 5 MHz to Hz: 5 × 1,000 × 1,000 = 5,000,000 Hz. Convert 3 GHz to MHz: 3 × 1,000 = 3,000 MHz.
Common mistakes
- Using wrong powers of ten — Frequency units use factors of 1,000, not 100. Converting MHz to kHz requires multiplying by 1,000, not 100.
- Forgetting the direction — Going from larger to smaller units (GHz → MHz) requires multiplication; going from smaller to larger (Hz → kHz) requires division.
- Mixing up MHz and MB — Megahertz (MHz) measures frequency, while megabytes (MB) measures data. They are different units.
Frequently asked questions
What is a Frequency Converter?
A Frequency Converter is a tool that converts frequency values between hertz, kilohertz, megahertz, and gigahertz.
How do I convert Hz to kHz?
To convert hertz to kilohertz, divide the frequency in Hz by 1,000. For example, 1,000 Hz ÷ 1,000 = 1 kHz.
What is the formula for MHz to GHz?
To convert megahertz to gigahertz, divide the frequency in MHz by 1,000. For example, 1,000 MHz ÷ 1,000 = 1 GHz.
How many Hz are in 1 MHz?
One megahertz (MHz) equals 1,000,000 hertz (Hz).
What is frequency measured in?
Frequency is measured in hertz (Hz), which represents cycles per second. Common multiples are kHz (10³ Hz), MHz (10&sup6; Hz), and GHz (10&sup9; Hz).
