Beats-per-minute calculator

Give tempo and time signature

BPM parameters

  • Beats-per-minute: 60 BPM
  • Beats-per-second: 1 Hz
  • Length of 1 beat: 1 second = 1000 msec
  • Length of 1 bar (4 beats): 4 second

    • Loop & song length

    These are the lengths of multiple beats (handy for calculating loop lengths, LFO)
    1 beat =1000ms =1Hz
    2 beats =2sec =0.5Hz
    3 beats =3sec =0.33Hz
    4 beats =4sec =0.25Hz
    6 beats =6sec =0.17Hz
    7 beats =7sec =0.14Hz
    8 beats =8sec =0.13Hz
    10 beats =10sec =0.1Hz
    12 beats =12sec =0.08Hz
    16 beats =16sec =0.06Hz
    24 beats =24sec =0.04Hz
    32 beats =32sec =0.03Hz
    These are the lengths of multiple bars/measures (handy for estimating the length of a song).
    2 bars =8 sec
    4 bars =16 sec
    8 bars =32 sec
    16 bars =64 sec
    24 bars =96 sec
    32 bars =128 sec
    40 bars =160 sec
    48 bars =192 sec
    60 bars =240 sec
    80 bars =320 sec
    100 bars =400 sec
    120 bars =480 sec

    Fractions → millisecs

    These are some common fractions (handy for setting delays and modulation parameters)
