Home / BPM to ms
BPM to ms calculator
Type a tempo to get every note length in milliseconds — straight, dotted and triplet — for setting delays, reverb pre-delay, compressor release and LFO rates. Or type a delay time to get its BPM.
The formula
quarter note (ms) = 60,000 ÷ BPM. Other values follow: half the quarter for an eighth, a quarter of it for a sixteenth, ×1.5 for dotted notes and ×⅔ for triplets. To go the other way, BPM = 60,000 ÷ ms. LFO rate in hertz is 1000 ÷ ms.
