Time converter
From nanoseconds to centuries. 12 units, converted from one table of exact factors.

Worth knowing. A month and a year here are averages, because neither is a fixed length. Anything that has to land on a date needs a calendar, not a multiplication.
1 minute in every other time unit
Computed by the same engine that runs the converter above, so these can never drift apart from it.

What each unit actually is
Most converters give you a number and stop. Where a figure is exact by definition we say so, and where it is an average or shifts with conditions we say that too — that is usually the thing you needed to know.
| Unit | Symbol | What it actually is |
|---|---|---|
| second | s | The SI base unit, defined by the caesium atom since 1967. |
| millisecond | ms | Exact. |
| microsecond | µs | Exact. |
| nanosecond | ns | Exact. |
| minute | min | Exact. |
| hour | h | Exact. |
| day | d | Exactly 86,400 seconds. A real solar day varies by a few milliseconds. |
| week | wk | Exact. |
| month | mo | An AVERAGE. The Gregorian year divided by twelve. No actual month is this length. |
| year | yr | The average Gregorian year, 365.2425 days. A common year is 31,536,000 s. |
| decade | decade | Ten average years. |
| century | century | One hundred average years. |
