How it works
For the displayed direction, 1 h equals 3600000000000 ns. The engine converts through the shared time base quantity. Listed units are fixed durations. Calendar months and years are excluded because their lengths depend on the calendar. The multiplier is derived from the two centralized unit factors. Keep full precision until the final result; displayed answers use up to 12 significant digits.
