The 60-Minute Hour
One hour is defined as exactly 60 minutes, and one minute equals 60 seconds. This sexagesimal (base-60) system dates back to the ancient Babylonians and remains the foundation of how we measure time today. To convert any number of hours to minutes, simply multiply by 60; to go the other way, divide the number of minutes by 60.
- Hours to minutes: minutes = hours × 60
- Minutes to hours: hours = minutes ÷ 60
Decimal Hours vs. HH:MM
Time can be written as decimal hours (for example, 1.5 h) or in the familiar hours-and-minutes format (1:30). Decimal hours are convenient for calculations and payroll, while HH:MM is easier to read on a clock. The fractional part of a decimal hour represents minutes: multiply it by 60 to find them. For instance, 0.25 h is 15 minutes, and 0.75 h is 45 minutes.
- 0.25 h = 15 minutes
- 0.5 h = 30 minutes
- 0.75 h = 45 minutes
