Timecard GuruHow this conversion works
The digits before the decimal point are the whole hours (1). The rest is a fraction of the next hour, not a minute count. Multiply that fraction by 60: 0.5 × 60 = 30. That is 1 hour and 30 minutes. If a form asks for decimal hours, enter 1.50. If it asks for hours and minutes, enter 1 hour and 30 minutes. 1.30 would be wrong: that is 1 hour and 18 minutes.
Do not read 1.5 as 1 hour and 5 minutes. 1.5 hours is 1 hour and 30 minutes, because 0.5 × 60 = 30.
