How It Works
Formula
result = value x (seconds in from unit) / (seconds in to unit)Each unit is expressed in seconds: a minute is 60, an hour is 3,600, a day is 86,400, a week is 604,800, and a year is 31,536,000 (365 days). The converter turns your value into seconds, then divides by the seconds in the target unit.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
How many seconds are in a year?
A 365-day year has 365 x 86,400 = 31,536,000 seconds. A leap year has 31,622,400 seconds.
How many minutes are in a day?
A day has 24 hours, and each hour has 60 minutes, so 24 x 60 = 1,440 minutes.
Common Time Conversions
How one of each unit converts into smaller units.
| 1 of unit | Seconds | Minutes | Hours |
|---|---|---|---|
| Minute | 60 | 1 | 0.0167 |
| Hour | 3,600 | 60 | 1 |
| Day | 86,400 | 1,440 | 24 |
| Week | 604,800 | 10,080 | 168 |
| Year (365 days) | 31,536,000 | 525,600 | 8,760 |
A year here uses 365 days. A leap year adds one day, which is 86,400 more seconds.
Common mistakes
- Using 360 days for a year. A standard year is 365 days, which is 31,536,000 seconds.
- Forgetting leap years. A leap year has 366 days, so it has 31,622,400 seconds, not 31,536,000.
- Mixing up minutes and seconds in a day. A day has 1,440 minutes but 86,400 seconds.
