Formula and method

150 min = 2.5 h = 9,000 s. Decimal hours differ from hours-and-minutes notation: 2.5 hours means two hours thirty minutes, not two hours five minutes. Enter a known value in the units shown; editing a result solves the conversion in reverse.

150 min = 2.5 h = 9,000 s

Assumptions and limitations

How should I use a rounded result?
