About these units
The hour (h) is a unit of time, equal to 3,600 seconds.
The second (s) is an SI base or derived unit of time.
Going the other way, 1 second = 0.00027777778 hours. Time conversions look trivial until months and years appear — a month is not 30 days and a year is not 365. This converter uses the astronomical averages (30.44 days and 365.2425 days) so long-range answers stay accurate.
