〰️ Frequency Conversion

Convert between frequency units for electronics, telecommunications, radio, and physics. Supports hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz), rotations per minute (RPM), and beats per minute (BPM).

Frequency conversion calculates equivalent measures across standardized metric, customary, and technical units using fixed mathematical ratios. Standardized in accordance with NIST Special Publication 811 and BIPM SI guidelines, enabling precision calculations between Hertz, kHz, MHz, GHz, and 2 additional units.

Metrological Standards & Base Equation

1 kHz = 1,000 Hz. 1 MHz = 1,000 kHz = 1,000,000 Hz. 1 GHz = 1,000 MHz. 1 RPM = 1/60 Hz.

All frequency conversion factors on this platform comply with NIST Special Publication 811 (Guide for the Use of the International System of Units) and the BIPM SI Brochure (9th Edition), utilizing exact rational ratios and IEEE-754 double-precision arithmetic to prevent rounding distortion.

Frequently Asked Questions

How do I convert MHz to GHz?

Divide MHz by 1,000 to get GHz. For example, 2,400 MHz ÷ 1,000 = 2.4 GHz.

What is the difference between Hz and RPM?

Hz measures cycles per second, while RPM measures rotations per minute. 1 Hz = 60 RPM. To convert RPM to Hz, divide by 60.
