145 BPM in Milliseconds: Delay Times and Note Lengths
At 145 BPM one beat (a quarter note) lasts 413.793 ms and one bar of 4/4 lasts 1.655 seconds. Below are the delay times for every note value, the same notes in Hz, bar and phrase lengths, samples per beat and the genres that typically sit at this tempo.
145 BPM at a glance
- One beat at 145 BPM lasts about 413.79 ms (60,000 divided by 145), an eighth note about 206.9 ms and a dotted eighth about 310.34 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 18,248.276 samples at 44.1 kHz and 19,862.069 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 6.621 seconds, and 3 minutes of music at this tempo holds 108.75 bars of 4/4.
- Going from 145 to 146 BPM shortens each beat by 2.834 ms, about 0.68% of the beat.
- An LFO synced to quarter notes runs at about 2.417 Hz; synced to whole bars of 4/4 it runs at about 0.6042 Hz.
