About This Conversion
Hours to minutes multiplies by 60, and comes up whenever a duration given in hours has to be scheduled, metered or billed in minutes: a three-hour parking limit, a 1.5-hour meeting block, an eight-hour shift split into calendar slots.
Fractional hours are the part worth checking. A quarter of an hour is 15 minutes, a third is 20, and a tenth is 6. Rates quoted per hour convert the same way, so a job billed at 0.4 hours is 24 minutes of work.
