Understanding Time to Decimal Conversion
Clock time uses 60 minutes per hour, while decimal hours use base-10 fractions. Convert minutes to decimal hours by dividing by 60; for example, 30 minutes is 0.50 hour and 45 minutes is 0.75 hour.
This distinction matters in payroll, timesheets and project billing. Keep seconds and rounding rules consistent across entries so repeated conversions do not create avoidable differences in total recorded time.
Methodology and Interpretation
Decimal hours convert minutes as a fraction of 60: hours + minutes/60. For example, 1 hour 30 minutes is 1.5 hours, not 1.30. Payroll systems may apply separate rounding rules that are not part of the mathematical conversion.
