Sobre o Frequency Converter

CPU clock speeds, radio bands, audio pitches and motor speeds all live on the frequency spectrum but quote different units. This converter moves between hertz and its SI multiples, revolutions per minute for motors and rad/s for physics — updating every field from one input. Whether you are tuning an antenna or converting 33⅓ RPM to hertz, the factors are exact.

Como usar o Frequency Converter

  1. Enter your frequency value.
  2. Select the unit it is measured in.
  3. Read all other units instantly.
  4. Swap units for the reverse conversion.

Principais recursos

How do I convert RPM to Hz?
Divide by 60 — one revolution per second equals one hertz, so 3600 RPM is exactly 60 Hz. The converter handles this automatically.
What is the relationship between Hz and rad/s?
One hertz is 2π radians per second (about 6.283 rad/s), since each cycle sweeps a full circle.
