| # | Input Value | From | To | Result | Formula Used | Timestamp |
|---|---|---|---|---|---|---|
| 1 | 3600 | Seconds | Hours | 1 | value × 1 / 3600 | |
| 2 | 2 | Weeks | Days | 14 | value × 604800 / 86400 | |
| 3 | 250 | Milliseconds | Seconds | 0.25 | value × 0.001 / 1 |
Formula Used
All conversions use seconds as the base unit. Each unit has a factor relative to one second. We compute:
value_in_seconds = value × factor[from_unit]
result = value_in_seconds ÷ factor[to_unit]
Exact factors
- 1 nanosecond (ns) = 1e-9 s
- 1 microsecond (μs) = 1e-6 s
- 1 millisecond (ms) = 1e-3 s
- 1 second (s) = 1 s
- 1 minute (min) = 60 s
- 1 hour (h) = 3,600 s
- 1 day (d) = 86,400 s
- 1 week (wk) = 604,800 s
Average factors
- 1 month (avg) = 30.436875 d ≈ 2,629,743.999 s
- 1 year (avg) = 365.2425 d ≈ 31,556,952 s
Months and years vary; we use astronomical averages for consistency.
