Time Converter
Convert a time amount into seconds, minutes, hours, days, weeks, average months, and average years. The form asks for a Time value and From unit, then shows hours as the main result with the other units listed underneath.
Use it for schedules, billing, study plans, workouts, project estimates, and quick duration checks. For clock-based elapsed time, the time duration calculator may be more specific; for work shifts, see the time card calculator.
How to use this calculator

Conversion formula
The calculator converts everything through seconds.
| Unit | Seconds |
|---|---|
| 1 minute | 60 |
| 1 hour | 3,600 |
| 1 day | 86,400 |
| 1 week | 604,800 |
| 1 month | 2,629,800 |
| 1 year | 31,557,600 |
Worked example: 2.5 hours × 3,600 = 9,000 seconds. Divide by 60 to get 150 minutes, or divide by 24 to get 0.104 days.
Months use the original average month of 30.44 days; years use 365.25 days. For age or calendar spans, use the age calculator.
