Frequently Asked Questions

How many minutes are in 1 hour?

1 hour = 60 minutes. Therefore, 2 hours = 120 minutes and 8 hours = 480 minutes.

How do I convert decimal hours to minutes?

Multiply by 60. For example, 7.25 hours = 435 minutes and 7.5 hours = 450 minutes. This converts duration; it does not calculate wages or billing rules.

How do I convert 2 hours 20 minutes to total minutes?

Can I convert minutes back to hours?

Yes. Swap the units to divide minutes by 60. For example, 90 minutes = 1.5 hours.

Is 0.1 hour the same as 10 minutes?

No. 0.1 × 60 = 6 minutes. A decimal hour is a fraction of 60 minutes, not a base-100 time display.
