Worked example: 0.4 decimal hours in hours and minutes
0.4 × 60 = 24 minutes. Round to 24 minutes, then divide into complete hours and the remainder: 0h 24m.
The decimal part is a fraction of sixty minutes, not a count of minutes. For this entry the fraction contributes 24 minutes before whole-minute rounding. Convert each original entry before summing if your policy rounds entries separately; rounding only the final total can give a different result.
Assumptions and limits
- Non-negative duration, rounded to nearest whole minute. Half-minute ties round upward.
- This is a duration, not a clock time or a pay-rounding recommendation.
- Unpaid breaks must be deducted separately; no overtime or wage rule is inferred.
