Worth knowing
- Decimal Time Converter on Toolspire: 1.5 hours is 1 h 30 m, and 90 minutes.
- 0.1 hour is 6 minutes, because an hour has 60 minutes and 0.1 × 60 = 6.
- 0.25 hour is 15 minutes.
- Negative hours are rejected. A duration here is a length, not a direction.
A tenth of an hour is six minutes
Decimal time multiplies the fraction of an hour by 60. 0.5 becomes 30 minutes. 0.1 becomes 6 minutes, which is the figure people miss when they treat the decimal as a clock minute. 1.5 hours is one hour and 0.5 × 60 minutes, so 1 h 30 m, or 90 minutes in total. The page rounds to the nearest minute. It does not add two durations. That is the time-duration page.
