Time to Decimal FAQ

Common questions and answers about time to decimal calculation

What is Time to Decimal conversion?

Time to Decimal conversion is the process of converting standard time format (such as 8 hours 30 minutes) to decimal hour format (such as 8.5 hours). This conversion method is widely used in payroll calculation, project timing, and attendance management systems because decimal format is more convenient for mathematical operations and system processing.

How to manually perform Time to Decimal calculation?

Manual time to decimal calculation is simple: divide the minutes by 60, then add to the hours. For example, the calculation for 8 hours 45 minutes is: 8 + (45 ÷ 60) = 8 + 0.75 = 8.75 hours. Our online calculator can automatically complete this process, ensuring calculation accuracy.

Why use decimal hours instead of traditional time format?
