What is this about?
This is a tempo calculator I programmed. I often used Peter Forret's Tempo Calculator but I wanted something I could use offline so I programmed this HTML5 & jQuery tool that requires no sending, posting and server-side languages. It works in any modern browser including mobile browsers.
Conversion Formulas
I often which various calculators also included the formulas, so here you go:
  • Milliseconds: [Time Sig divided]*240/{note division}/BPM*1000 = ms
    • e.g. [4/4]*240/{16}/120*1000 = 125 ms
  • Hertz: BPM/([Time Sig divided]*240/{note division}) = hz
    • e.g. 140/([3/4]*240/{8}) = 6.22 hz
