Total decimal hours (e.g. 27.5)—whole days and remaining hours.
Whole days = ⌊total hours ÷ 24⌋. The remainder hours are shown with two decimals (total − 24×days). Input must be a finite non‑negative number; comma decimals are accepted.
This calculator uses plain decimal numbers. If a result looks wrong, check whether you used a comma instead of a dot (or vice versa) where the field expects one.
