To convert hours to minutes, multiply by 60. One hour is defined as exactly 60 minutes, making this an exact whole-number conversion:
1 hr = 60 min = 3,600 sec. 24 hr = 1,440 min. 1 week = 10,080 min.
Useful time benchmarks for hours and minutes:
To convert hours to minutes, multiply by 60. One hour is exactly 60 minutes by definition. For example, 2.5 hours = 2.5 × 60 = 150 minutes. A standard 8-hour workday = 8 × 60 = 480 minutes. One full day (24 hours) = 24 × 60 = 1,440 minutes.
To go the other way (minutes to hours), divide by 60. For example, 90 minutes = 90 ÷ 60 = 1.5 hours. If you have a time in hours and minutes (e.g. 2h 45min), convert to minutes as: (2 × 60) + 45 = 165 minutes.
Converting hours to minutes is useful when scheduling events (booking slots in a calendar), cooking and baking (timing recipes in minutes), exercise and fitness (workout duration), media (film and podcast lengths), travel (journey time calculations), and data analysis where timestamps are stored in minutes. Many scheduling apps and productivity tools work in minutes rather than fractional hours.
There are exactly 60 minutes in one hour. This is a fixed definition. To convert hours to minutes, multiply by 60. To convert minutes back to hours, divide by 60.
1.5 hours = 1.5 × 60 = 90 minutes. Similarly, 2.5 hours = 150 minutes and 0.75 hours = 45 minutes.
One day has 24 hours × 60 minutes = 1,440 minutes. One week = 7 × 1,440 = 10,080 minutes. One year = 365 × 1,440 = 525,600 minutes.
Multiply the hours by 60 and add the remaining minutes. For example, 3 hours 25 minutes = (3 × 60) + 25 = 180 + 25 = 205 minutes.
