Frequently Asked Questions
Everything you need to know about decimal conversions, accuracy, and formulas.
01How do you convert decimal hours into hours and minutes?▼
To convert decimal hours into hours and minutes: 1) The integer number before the decimal point is the total whole hours. 2) Take the decimal fraction after the point and multiply it by 60 to calculate the minutes. For example, 7.4 hours = 7 hours and (0.4 × 60) = 24 minutes.
02Why do payroll and timesheet software use decimal hours?▼
Accounting, payroll, and billing software require standard numerical decimal format (e.g. 8.25 hours) rather than colon time (8:15) to perform arithmetic multiplications with hourly pay rates (e.g. 8.25 × $40/hr = $330.00).
03What is the 6-minute / 10th of an hour billing system?▼
Many legal, medical, and consulting firms bill clients in 6-minute increments (0.1 hours). For example, 1 to 6 minutes = 0.1 hr, 7 to 12 minutes = 0.2 hr, and so forth.
