Why decimal hours?
Payroll software multiplies hours by wage rate — and that only works when time is a plain number. 7 hours 30 minutes × $20/hour needs decimal format: 7.5 × $20 = $150. Every conversion on this site exists to bridge the gap between how humans read clocks and how software does math.
