What Is 30 Minutes on a Timesheet?

30 minutes on a timesheet is half an hour, commonly represented as 0.5 in decimal format for easier calculations. 

In time tracking and payroll, hours are often tallied in decimals. So, 6 hours and 30 minutes worked would be recorded as 6.5 hours. This simplifies summing hours and ensures accuracy on paychecks.

Most organizations break hours into quarter-hour increments. Key conversions include:

• 15 minutes = 0.25 hours (a quarter hour)
• 30 minutes = 0.50 hours (half an hour)
• 45 minutes = 0.75 hours (three-quarters of an hour)

Using these, if someone works from 9:00 to 5:30 (with no break), they’ve worked 8.5 hours (8 hours + 30 minutes).

On a paper or Excel timesheet, to convert 30 minutes to a decimal, divide by 60: 30 ÷ 60 = 0.5. 

This conversion is straightforward because 30 is exactly half of 60. Many QuickBooks integrations and payroll systems expect hours in decimal, so it’s standard to convert minutes this way. 

Most digital time trackers will do these conversions automatically once you input start and end times. (check our Timecamp review)

Some employers round time entries to the nearest quarter hour. For instance, if someone clocks out at 5:32, the system might round it to 5:30 (which is 30 minutes past 5:00) as 5.5 hours after 12 noon. 

Official U.S. labor guidelines, like the Alabama or North Dakota labor laws, allow rounding in 15-minute increments as long as it doesn’t consistently favor the employer or employee. But regardless, 30 minutes will consistently equal 0.5 hours in records, which is easy to verify. 

Accurately logging 30-minute breaks is also crucial. If employees take a half-hour lunch, that 0.5 hour is typically unpaid, so it should be subtracted from total hours worked. For example, an 8:00–4:30 shift with a 30-minute lunch is 8 hours total on the timesheet, not 8.5.

In summary, 30 minutes equals 0.50 hours on a timesheet. Whether you’re tracking manually or using software, using the decimal .50 ensures your half-hour increments are counted correctly, keeping payroll precise and fair.
