Most of our calculators are in google sheets are are either stand-alone or embedded.

Those embedded into our site (https://www.cyclingapps.net/calculators) should allow direct editing into the input cells.

If you open a calculator in google sheets you either have to ask for edit permission or make a copy (which will make a copy to your google drive):

Occasionally, you might come across a calculator which is locked, then you will have to email us.
