Minutes to Hours Converter (min to h)

Payroll systems, invoices and project trackers usually want time as decimal hours, while clocks and stopwatches give minutes. Converting 45 minutes to 0.75 h, or 1 hour 20 minutes to 1.33 h, is the step that turns a timecard into a number that can be multiplied by an hourly rate.

Decimal hours can look odd at first: 1.5 h is an hour and a half, not 1 hour 50 minutes. Many law and consulting firms bill in tenths of an hour, so a 6-minute phone call is billed as 0.1 h and a 20-minute one as roughly 0.3 h, depending on the firm's rounding rule.

How to use this tool

1. Type a value in the Minute box to see it in hours, or type in the Hour box to convert the other way.
2. Press ⇄ to swap the two units, or Load example for a typical value.
3. Check the charts below for common values; for other units, open the Time converter.

Formula

Hour (h) = Minute (min) × 0.0166666666667

Minute (min) = Hour (h) × 60

Both factors come from exact definitions: 1 hour = 60 minutes and 1 minute = 0.0166666666667 hours (shown to 12 significant digits).

Example

Two conversions worked with the same factors the converter uses:

45 min × 0.0166666666667 = 0.75 h

1.75 h × 60 = 105 min

Durations counted in minutes

Quick mental estimate

Divide by 60, or count in 6-minute blocks: each 6 minutes is 0.1 h, so 42 minutes is 0.7 h. Because an hour splits evenly into ten 6-minute blocks, the block method is exact whenever the minutes are a multiple of 6.

Use the converter or the charts when the exact figure matters.

The two units

Minute (min): A minute is exactly 60 seconds. It is not an SI unit, but the BIPM lists it with the hour and day as units accepted for use with the SI.

Hour (h): An hour is 60 minutes, or exactly 3,600 seconds, and is accepted for use with the SI. The fixed-duration day used here contains 24 hours.
