Fred:

"How much string was on ball of string at the beginning" --MINUS--
"How much string is on the ball when you have cut the string off you
need" = L(length of string)

gessh! amateurs really should know that formula!
tongue-in-cheek

I just hate having to unwind the ball, measure the string, then do it
again after cutting!
