Time Unit Pairs

140 conversion pages for time units, each with its exact factor, the formula and a reference table.

The Time Unit Pairs collection covers 140 pages of time units — one page for each ordered pair of units, so there is nothing to configure before you get an answer.

Conversions are split one per direction rather than collapsed into a single dual-dropdown tool. It means “Centuries to Fortnights” lands on a page about exactly that, with the right examples and the right reference table, instead of a generic converter you have to set up before it tells you anything.

Every page states the exact factor it uses, writes the formula out in full, and shows the arithmetic applied to real numbers rather than only handing you an answer. Where a factor is defined rather than measured — an inch is exactly 25.4 mm, a pound exactly 0.45359237 kg — the page says so, so you can see the result is exact and not a rounded approximation of an approximation.

This collection reaches across the extremes of the time scale — nanoseconds and picoseconds at one end, fortnights, quarters and millennia at the other. Sitting in Time Units, it links back to the sibling collections that share its units, so a chain of conversions never needs a second tab.
