Why payroll uses decimal hours

Pay is calculated by multiplying hours by an hourly rate, and that only works with decimal numbers: 7 h 45 min at $20 per hour is 7.75 × $20 = $155, not 7.45 × $20. A common mistake is to type 7.45 for 7 hours 45 minutes, which underpays by 18 minutes.

Quarter-hour rounding converts to .25 (15 min), .50 (30 min) and .75 (45 min).
