Calculating working hours can be complicated due to the challenge of converting hours and minutes to decimals. In this post, we’re sharing a free time card conversion chart, calculator, and formula to make the process much easier for you.
What is time card conversion?
Time card conversion is the process of turning the total hours employees have worked into decimal values that can be easily added together to calculate their total hours and pay. This process is important because accurate values ensure that employees are properly compensated for their time.
Time card conversion formula
To convert work hours into decimals, you keep the number of total hours worked the same, divide the minute number by 60, then add the result of that calculation to the hour number. For example, say an employee worked 7 hours 45 minutes. Divide 45 by 60 to get 0.75. Then, add that to 7 to arrive at a total of 7.75 hours in decimal format.
Time card conversion chart
While you could do all of these calculations by hand, we’ve created the time card conversion chart below to make it easier. Instead of performing the calculations, simply find the number of minutes worked in the chart below and add the respective decimal value to the hours worked.
