Field notes
The homepage sorts 40 calculators into six categories and gives each a short input-and-output description, from tile boxes and wallpaper repeats to ad revenue based on page views and an assumed RPM. It says each tool includes its formula, assumptions, and a worked example. Three featured guides narrow the focus further to UK gardening, candle stock and orders, and planning photo crops and mat openings.
