How many hours in a day, minutes in an hour
The core time relationships are fixed and build on the second, the SI base unit of time.
| Unit | In seconds | Plain equivalent |

| 1 minute | 60 | 60 seconds |
| 1 hour | 3,600 | 60 minutes |
| 1 day | 86,400 | 24 hours, 1,440 minutes |
| 1 week | 604,800 | 7 days, 168 hours |
| 1 month | 2,629,746 | 30.44 days on average |
| 1 year | 31,557,600 | 365.25 days on average |
Why months and years use average lengths
A month holds 28 to 31 days and a year can be a leap year. To keep conversions reversible, the calculator uses average values: 30.44 days per month and 365.25 days per year. This is the standard way to convert durations rather than calendar dates.
When you need the exact interval between two specific dates — including month lengths, leap days and weekends — count it on a calendar instead of converting average durations.
Converting time by hand
- Minutes to hours: divide by 60. 150 minutes ÷ 60 = 2.5 hours, which is 2 hours 30 minutes.
- Hours to minutes: multiply by 60. 7.25 hours × 60 = 435 minutes.
- Seconds to hours: divide by 3,600. 5,400 seconds ÷ 3,600 = 1.5 hours.
- Days to hours: multiply by 24. 3 days × 24 = 72 hours.
- Turn a decimal hour into minutes by multiplying by 60: 0.4 hours × 60 = 24 minutes.
Where time conversion helps
- Reading shift, travel or workout durations in the unit you actually think in.
- Translating technical specifications that state durations in seconds.
- Planning deadlines: how many weeks fit into 90 days, or how many hours a work month holds.
- Checking homework and everyday questions about hours, minutes and seconds.

How many hours are in a day?
A day has 24 hours, which is 1,440 minutes or 86,400 seconds.
