Decimal hours (payroll)

Payroll software wants 7.75 hours, not "7 h 45 min". Both formats shown side-by-side above.

Common uses

Timesheets: net hours after break — enter start/end/lunch for instant payroll decimals.
Night shifts: tick "next day" — 22:00 to 06:00 correctly returns 8 hours, not -16.
Flight & travel: gate-to-gate time without timezone confusion (same-day flights).
Workouts & study: total focused time minus rest intervals.

Decimal shortcut: minutes ÷ 60. 45 min = 0.75 hr, 30 min = 0.5 hr, 15 min = 0.25 hr, 6 min = 0.1 hr.
