For completeness and to close the thread, I suspect the OP had noticed that a time in excel is a decimal of a day (a day being 1), so 12 noon is .5 and so on.
So to multiply times by hourly rate for example, you have to multiply the hours by 24 to get days, so, if you have a time of 8 hours at £20 per hour then the formula would be With time in A1 and rate in B1
=(A1*24)*B1
Should give you 160
