Beats-per-minute calculator

Give tempo and time signature

BPM parameters

  • Beats-per-minute: 120 BPM
  • Beats-per-second: 2 Hz
  • Length of 1 beat: 0.5 second = 500 msec
  • Length of 1 bar (4 beats): 2 second

    • Loop & song length

    These are the lengths of multiple beats (handy for calculating loop lengths, LFO)
    1 beat =500ms =2Hz
    2 beats =1000ms =1Hz
    3 beats =1.5sec =0.67Hz
    4 beats =2sec =0.5Hz
    6 beats =3sec =0.33Hz
    7 beats =3.5sec =0.29Hz
    8 beats =4sec =0.25Hz
    10 beats =5sec =0.2Hz
    12 beats =6sec =0.17Hz
    16 beats =8sec =0.13Hz
    24 beats =12sec =0.08Hz
    32 beats =16sec =0.06Hz
    These are the lengths of multiple bars/measures (handy for estimating the length of a song).
    2 bars =4 sec
    4 bars =8 sec
    8 bars =16 sec
    16 bars =32 sec
    24 bars =48 sec
    32 bars =64 sec
    40 bars =80 sec
    48 bars =96 sec
    60 bars =120 sec
    80 bars =160 sec
    100 bars =200 sec
    120 bars =240 sec

    Fractions → millisecs

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