How to convert seconds to hours
A day here is a duration of 86,400 seconds. Unless explicitly labeled Julian, months and years use the mean Gregorian convention (365.2425 days per year; one twelfth per month), rather than the actual length of a particular calendar interval.
h = s ÷ 3600One hour corresponds to 3600 seconds, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
