bpm charts and how to use them

hey guys im kinda curious if theres ever been a cheat sheet on compatiable bpm. say we have a patch phrase at tempo 100 but u wanna fit it to a new tempo at 233 and a note value at 1/8 what would be the new tempo for the patch phrase to fit into 1/8?

if there is such a bpm chart, i need a chart that can show me a note value from 1/4 to 1/512 and all its compatiable tempos. if possible also whats the math used to figure this out to create a bpm chart?

no i know about this, im talkn about either the math involved to figure this out or a bpm chart already laid out for me like a multiplication chart (<--analogy) kinda. u know what i mean. ya i use these calculators alot lol there great but the **** who made this calculator wont give up the info how he used math to create this, i wanna know how he **** did this. but lets keep this thread on topic back to my topic starter question

the math he used can be found there :

read carrefully you will easyly find the math behind the javascript code.

if your new tempo is 233, 1/8 would be like half of the tempo, because 1/8 is half of 1/4.

dude i love u. my buddy i know knows java in and out. he can prolly help me figure what this all means, like whats the java part and the math part btu thats if it is the formulas to those calculators on this java script u gave me. thanks a bunch man u went all out for me lol. i was doin a search for a bpm chart and i found one hjow accurate it is i dont know yet cause i havent used it but if u guys want to see what im talkn about bpm chart heres one. http://www.electronicmusic.com/features ... rsion.html
