OraHow to convert minutes
Divide minutes by 60, then add the result to the whole hours. For example, 7 hours 45 minutes is 7 + 45 ÷ 60 = 7.75 decimal hours. Seven hours 30 minutes is 7.50, not 7.30: in decimal hours, 7.30 means 7 hours 18 minutes.

| 10 | 0.17 |

Minutes and decimal hundredths are different units: 30 minutes is 0.50 hours. The time-card mistakes guide shows why mixing them can distort a total; use the time-card calculator when you need to add several dated shifts.
Convert back to hours and minutes
Keep the whole hours, multiply the decimal fraction by 60, then round to the nearest minute. For example, 7.75 hours is 7 hours 45 minutes. The converter accepts up to four decimal places; longer decimal fractions need to be rounded before entry.
Why rounded totals can differ
Choose zero to four places for the decimal display; reverse conversion rounds to the nearest minute. Rounding each entry separately can differ from rounding the final total. For example, at two places three one-minute entries display as 0.02 hours each, but their combined three minutes display as 0.05 hours. Keep the original minutes when accurate totals matter.
