Firstly let me apologise for my lack of maths skills!! I work as a sports coach and I知 very adept at the day to day calculations I need but I知 building a spreadsheet and have hit a problem.

Basically I need to calculate how many times a number has to be doubled to match a larger number. For example 250 meters (0.25km) has to be doubled twice to match 1km. Ideally I need to calculate this with numbers that don稚 really fit.

For example 0.4km into 1km!!?? Or 1km into 5km??

Any help would be appreciated and sorry if this is super simple as so am!
