Minutes to hours divides by 60. A 90-minute movie is 1.5 hours; a 270-minute marathon is 4.5 hours. The conversion is sexagesimal — base 60 — which is why timesheet software so often gets it wrong: 1 hour 30 minutes is 1.5 in decimal hours, not 1.30. Payroll calculations always need decimal hours for multiplication by hourly rates; presentation back to humans usually wants the hh:mm format.
Freelance and legal billing tracks work in minute increments but invoices in decimal hours: 135 min of consulting is 2.25 h, and a quick 50 min call is 0.833 h, typically rounded up to the nearest quarter-hour per firm policy. The rounding rule matters more than the arithmetic — a shop billing in 15-minute blocks turns that 50 min call into a full 1 h charge, so check the increment before trusting a raw division.
