Time converters
Time conversions look simple but hide a definition problem: the calendar year is not exactly 365 days. We use the Julian year (365.25 days), which is also the IAU definition behind the light year, so all our derived units are internally consistent. For everyday use this difference matters only at the multi-year scale.

Time units in terms of the second
Every time unit on Convertitive is defined as an exact ratio of the second (s), the reference unit for this category. The table below shows what one of each unit equals in seconds — the constant every converter on this page is built from.
| Unit | Symbol | 1 unit in seconds |
|---|---|---|
| Seconds | s | base unit |
| Milliseconds | ms | 0.001 s |
| Microseconds | µs | 1.0000 × 10^−6 s |
| Minutes | min | 60 s |
| Hours | h | 3600 s |
| Days | d | 86400 s |
| Weeks | wk | 604800 s |
| Years | yr | 31557600 s |
To convert between any two units, Convertitive scales the input to seconds using these factors and then back out to the target unit — so every result on this page traces to a single, exact definition rather than a chained approximation. Pick any pair above to see the formula, a 50-row reference table, and worked examples.
