A simpler and more acurate formula is:
Take whatever unit of measure you used the first time and raise it to the

real time is 10 hours, one hour really takes two days, etc..

The best formula for calculating time needed for a particular job is as
follows:
The first 90% of the job takes 90% of the time
The last 10% of the job takes another 90% of the time.
