How to calculate
Type the number of hours and read the minutes below. To convert by hand, multiply hours by 60: 1.5 hours is 1.5 × 60 = 90 minutes. To convert minutes back to hours, divide by 60. Decimal hours work too — 0.25 hours is 15 minutes — so you can turn a timesheet's 2.75 hours into 165 minutes instantly.
minutes = hours × 60, where 60 is the exact number of minutes in one hour. Equivalently, hours = minutes ÷ 60. One hour is also 3,600 seconds, so seconds = hours × 3,600 if you need the smaller unit.
Example calculation
2 hours multiplied by 60 minutes per hour is 120 minutes. An hour is defined as exactly 60 minutes (and 3,600 seconds), so any duration in hours converts to minutes by multiplying by 60.

Assumptions
- One hour is exactly 60 minutes and 3,600 seconds, so the conversion is exact.
- This treats time as a plain duration; it does not handle clock arithmetic across midnight or time zones.
- Leap seconds are ignored, as they are for virtually all everyday timekeeping.
Common mistakes
- Reading a decimal hour as hours-and-minutes — 2.5 hours is 2 hours 30 minutes, not 2 hours 50 minutes.
- Using 100 instead of 60 when converting, a habit carried over from decimal math that does not apply to clock time.
- Reversing the direction — multiply by 60 for minutes, divide by 60 for hours.
