Time calculator: minutes to hours
Type a value in either box, and the answer shows it in the other unit as you type.
- Hours (h)
- 0.016667
1 min = 0.016667 h (0 h 1 min).
- Hours and minutes
- 0 h 1 min
Hours (h): 0.016667. 1 min = 0.016667 h (0 h 1 min).
Hours (h) by minutes (min)
How to calculate
Converts minutes (min) to hours (h) and back, with the exact unit definitions.
Example with the default inputs (Minutes (min) 1): 1 min = 0.016667 h (0 h 1 min).
Formula: h = min × 0.0166666666667 (the same as min ÷ 60)
- 1 minute = 0.0166666666667 hours, from the exact definitions in NIST SP 811.
- Exact on the typed decimals: at most 6 decimal places (6 significant digits below 0.0001), rounded half up.
- Hours and minutes use the box you typed; minutes round half up to 0.01, and 60.00 carries.

Other questions people ask
How many hours are in a minute?
1 minute is 0.016667 hours, from the exact unit definitions (NIST SP 811).
How do I convert minutes to hours?
Multiply by 0.016667: h = min × 0.0166666666667 (the same as min ÷ 60). For example, 1 min × 0.016667 = 0.016667 h.
How do I convert hours back to minutes?
Multiply by 60, or type the hours into the second box and the converter works it out. 1 hour is 60 minutes.
How do I turn minutes into hours and minutes?
Divide by 60. The whole number is the hours, and the rest × 60 is the minutes. 135 minutes is 2.25 hours, which is 2 hours and 0.25 × 60 = 15 minutes.
What is 0.5 hours in minutes?
30 minutes. Decimal hours are fractions of 60 minutes: 0.25 h = 15 min, 0.5 h = 30 min, 0.75 h = 45 min. Timesheets often use decimal hours.
How are the minutes rounded?
The hours-and-minutes line rounds the minutes half up to 0.01 minute. If they round to 60.00, they count as one more hour.
