151 BPM at a glance

  • One beat at 151 BPM lasts about 397.35 ms (60,000 divided by 151), an eighth note about 198.68 ms and a dotted eighth about 298.01 ms.
  • A beat here is not a whole number of milliseconds. The nearest tempo where it is: 150 BPM, with 400 ms per beat.
  • A beat is 17,523.179 samples at 44.1 kHz and 19,072.848 samples at 48 kHz, neither a whole number, so sample accurate loop points round slightly at both rates.
  • A 4 bar phrase in 4/4 takes about 6.358 seconds, and 3 minutes of music at this tempo holds 113.25 bars of 4/4.
  • Going from 151 to 152 BPM shortens each beat by 2.614 ms, about 0.66% of the beat.
  • An LFO synced to quarter notes runs at about 2.517 Hz; synced to whole bars of 4/4 it runs at about 0.6292 Hz.
