About This Calculator

This calculator converts tempo (BPM) to millisecond durations for various musical note subdivisions. Use these values for delay effects, sequencers, or synchronizing audio with visual elements.

The BPM Calculator is an essential tool for musicians, producers, and audio engineers who need precise timing values for musical note subdivisions. Enter any tempo (in beats per minute) and instantly see the duration in milliseconds for:

  • Standard notes: whole, half, quarter, eighth, sixteenth, and 32nd notes
  • Dotted variations: notes extended by 50% (1.5x)
  • Triplet variations: three notes in the space of two (2/3x)

Use Cases

Audio Production

  • Set delay times that sync perfectly with your track’s tempo
  • Configure LFO rates for rhythmic modulation effects
  • Time reverb pre-delay to groove with the music

Live Performance

  • Program step sequencer timing
  • Sync visual effects to musical beats
  • Calculate loop lengths for seamless phrase looping

Web Development

  • Synchronize animations with musical timing
  • Build rhythm-based games or interactive experiences
  • Create music visualizers with accurate beat detection

How It Works

The calculator uses the fundamental relationship between tempo and time:

  • At 120 BPM, each beat (quarter note) lasts exactly 500 milliseconds
  • This is calculated as: 60,000ms / 120 BPM = 500ms
  • All other subdivisions derive from this base value

Try different tempos to see how timing changes across the musical spectrum, from slow ballads (~60 BPM) to fast electronic music (~140+ BPM).
