About these units
The day (d) is a unit of time, equal to 86,400 seconds.
The hour (h) is a unit of time, equal to 3,600 seconds.
Going the other way, 1 hour = 0.041666667 days. 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.
