How to convert minutes to decimal hours

Divide the minutes by 60. 45 minutes is 45 ÷ 60 = 0.75 hours, so 7 hours 45 minutes is 7.75 hours. Payroll systems, invoices and spreadsheets use decimal hours because they can be multiplied by a pay rate: 7.75 hours × $20 = $155.

To go back from decimal hours to minutes, multiply the decimal part by 60: 0.4 hours × 60 = 24 minutes, so 8.4 hours is 8 hours 24 minutes.

Don’t read decimal hours as minutes. 8.30 decimal hours is 8 hours 18 minutes, not 8 hours 30 minutes, and 8.5 hours is 8 hours 30 minutes.

Tenths of an hour (6-minute increments)

Some employers pay, and many professionals bill, in tenths of an hour (6-minute steps). Billing often rounds up to the next tenth; this chart rounds to the nearest one:

Minutes to the nearest tenth of an hour
Minutes	Tenths	Minutes	Tenths
1–2	0.0	33–38	0.6
3–8	0.1	39–44	0.7
9–14	0.2	45–50	0.8
15–20	0.3	51–56	0.9
21–26	0.4	57–60	1.0
27–32	0.5

Rounding to the nearest tenth: 0.05 hours is 3 minutes, so minutes 1–2 round down to 0.0 and minute 3 rounds up to 0.1. Many payroll rules round 3 minutes down instead; check yours.

Converting a whole time card

Paste or type one time per line in Convert a list, for example each day’s hours from a paper time card. You get each one in decimal hours and the total. Add the times first and convert the total once, rather than rounding each day: five days of 7:20 is 36:40, or 36.67 hours, while adding five rounded 7.33s gives 36.65.

Frequently asked questions

How do I convert minutes to decimal hours?

Divide the minutes by 60. 15 minutes = 0.25 hours, 30 minutes = 0.5, 45 minutes = 0.75 and 20 minutes = 0.33 (rounded). For hours and minutes, add the whole hours: 6:45 = 6.75 hours.

What is 1 hour and 45 minutes in decimal?

1.75 hours: 45 minutes ÷ 60 = 0.75, plus the 1 hour.

What is .25 of an hour?

15 minutes. Multiply the decimal by 60: 0.25 × 60 = 15. Likewise 0.5 hours is 30 minutes and 0.75 hours is 45 minutes.

What is .23 of an hour?

About 14 minutes: 0.23 × 60 = 13.8 minutes, which rounds to 14.

What is .42 of an hour?

About 25 minutes: 0.42 × 60 = 25.2 minutes. In the chart, 25 minutes is 0.42 hours.

Why does payroll use decimal hours?

A pay rate is per hour, so hours have to be a single number to multiply by it. 7 hours 30 minutes at $18 an hour is 7.5 × $18 = $135; you can’t multiply 7:30 by $18 directly.

How do I convert decimal hours to hours and minutes in Excel?

In Excel, divide the decimal hours by 24 and format the cell as [h]:mm. For example =A2/24 shows 7.75 as 7:45. To go the other way, multiply a time cell by 24 and format it as a number: =A2*24.

Should I round each day or the total?

Convert the total if you can. Rounding each day to hundredths and then adding can be a few hundredths off. Your employer’s payroll rules decide which one counts.
