Ten minutes is easy to understand on a clock, but writing those 10 minutes as a decimal can cause a little confusion. Is it 0.10 hours, 0.1667 hours, or 0.167 hours?
The answer depends on how you round the decimal.
How to Convert 10 Minutes to Decimal Hours
Converting minutes to decimal hours is simple: divide the number of minutes by 60.
Why 60? Because one hour contains 60 minutes.
For 10 minutes: 10 ÷ 60 = 0.1666…
You can also simplify the fraction first: 10/60 = 1/6
And 1/6 as a decimal is: 0.1666…
So, 10 minutes in decimal is 0.1666… hours, or approximately 0.167 hours when rounded to three decimal places.
Why Are Some Answers 0.1667 and Others 0.167?
You may find different answers when searching for 10 minutes in decimal. That’s because the number is a recurring decimal.
If a worksheet asks for the answer to three decimal places, use 0.167. If it asks for four decimal places, use 0.1667.
Is 10 Minutes 0.10 Hours?
No. This is a common mistake.
It may seem that 10 minutes should become 0.10 hours because the number 10 appears after the decimal point. But decimal hours do not divide an hour into 100 minutes.
An hour has 60 minutes, so you must use 60 as the denominator:
10 ÷ 60 = 0.1666…
For comparison, 0.10 hours is actually 6 minutes, because:
0.10 × 60 = 6 minutes
10 ÷ 60
0.10 × 60
The important idea is simple: when converting minutes to decimal hours, divide by 60, not 100.
What Is 1 Hour 10 Minutes in Decimal?
This is just as easy once you know how to convert the minutes.
Start with the whole hour, then convert the extra 10 minutes:
1 hour 10 minutes = 1 + (10 ÷ 60)
= 1 + 0.1666…
= 1.1666… hours
So, 1 hour 10 minutes is 1.1666… hours, or approximately 1.167 hours to three decimal places.
The general rule is:
Decimal hours = Whole hours + (Minutes ÷ 60)
