How to convert BPM to milliseconds

The formula to convert BPM to milliseconds per quarter note is:

ms per quarter note = 60,000 / BPM

For example, at 120 BPM each quarter note lasts 60,000 / 120 = 500 ms. To get other note values, divide or multiply:

Producers use BPM-to-millisecond conversion when:

Setting delay times in plugins that don't sync to host tempo (e.g., 1/8 dotted delay at 120 BPM = 375 ms)
Calculating LFO rates when modulating filters or pans in time with the beat
Pre-delay on reverb for tempo-locked spatial effects
Tape delay emulation on hardware units that use raw ms input
Sidechain attack/release tuning relative to the kick pattern
