hours to minutes formula
To convert hours to minutes, multiply the number of hours by 60. In symbols: min = h × 60.
One hour equals 60 minutes, and one minute equals 0.0166666666667 hours. An hour is exactly 60 minutes, so the factor is exact and has no rounding.
Worked example
Suppose you have 2.5 hours and need the answer in minutes.
- Write the formula: min = h × 60.
- Put in the number: 2.5 × 60 = 150.
- Round to suit the job. 150 min is accurate enough for most everyday uses.
So 2.5 h is 150 min. To check, convert back: 150 min is 2.5 h.

Where you will use it
Timesheets, flight durations, cooking times and billing are often stated in decimal hours, such as 2.5 hours, but schedules need minutes. Payroll rounding depends on this conversion.
Quick mental math
Multiply the decimal part by 60: 2.5 hours is 2 hours and 0.5 x 60 = 30 minutes, so 150 minutes.
