How do you read a time-to-decimal chart?
Find the minute value in the first column and read its decimal-hour equivalent in the second. The chart rounds repeating values to two decimal places, while the calculator preserves exact minutes.
The exact column shows four decimal places and the hundredth column is explicitly labeled as rounded. Original minutes remain authoritative.
Decimal hours = minutes ÷ 60.
Worked example
Thirty minutes appears as 0.50 decimal hours, while 20 minutes appears as 0.33 when rounded to two decimal places.
Important cases
- One minute is 0.0167 hours to four decimal places and 0.02 when rounded to a hundredth.
- Quarter hours convert exactly: 15 = 0.25, 30 = 0.50, and 45 = 0.75.
