How the conversion works
Multiply by 0.0002777777778 to go from second to hour, or divide by it to go back. Every conversion on this site routes through the SI value (s) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? hour to second — 1 h = 3,600 s.
