How to Convert a Time or Duration to Decimal Hours, Minutes and Seconds

Sometimes you need to know the total time in hours, minutes, or seconds and you need to convert. There are a few ways to convert a time to decimal like this. The calculator above is the easiest way, but there are some simple formulas to convert the time in different units.

The formulas below show how to convert a time duration to decimal form.

time in hours = H + (M ÷ 60) + (S ÷ 3,600)
time in minutes = (H × 60) + M + (S ÷ 60)
time in seconds = (H × 3,600) + (M × 60) + S

There are 60 minutes in 1 hour and 60 seconds in 1 minute. Knowing this, we can then find that there are 3,600 seconds in 1 hour (60 × 60 = 3,600.

For example, convert the time of 6:15:30 to hours.

time in hours = 6 + (15 ÷ 60) + (30 ÷ 3,600)
time in hours = 6 + 0.25 + 0.0083
time in hours = 6.2583

For example, convert the time of 6:15:30 to minutes.

time in minutes = (6 × 60) + 15 + (30 ÷ 60)
time in minutes = 360 + 15 + 0.5
time in minutes = 375.5

For example, convert the time of 6:15:30 to seconds.

time in seconds = (6 × 3,600) + (15 × 60) + 30
time in seconds = 21,600 + 900 + 30
time in seconds = 22,530
