What Are Military Minutes?

Military minutes are minutes written as decimal fractions of an hour. The term comes from payroll, where 24-hour time cards are totaled in decimal hours: 8 hours 15 minutes is entered as 8.25. Military time itself does not change minutes; 1445 still means 45 minutes past 2 PM.

How to Convert Minutes to Decimal Hours

To convert minutes to decimal hours, divide the minutes by 60 and round to 2 decimal places. An hour has 60 minutes, not 100, so minutes cannot be copied after the decimal point.

  • 15 minutes ÷ 60 = 0.25 hours
  • 20 minutes ÷ 60 = 0.33 hours
  • 35 minutes ÷ 60 = 0.58 hours
  • 7 hours 50 minutes = 7 + 0.83 = 7.83 hours

How to Convert Decimal Hours Back to Minutes

To convert decimal hours to minutes, multiply the decimal part by 60. 7.4 hours → 0.4 × 60 = 24 minutes → 7 hours 24 minutes. 0.75 hours × 60 = 45 minutes.

Military Time to Decimal Hours on a Time Card

To turn a military time card into decimal hours, find the hours worked, then divide the leftover minutes by 60.

  1. Clock in 0730, clock out 1615.
  2. 1615 − 0730: borrow 1 hour → 15 h 75 min − 7 h 30 min = 8 hours 45 minutes.
  3. 45 ÷ 60 = 0.75 → 8.75 decimal hours.

The military time card calculator runs these steps for a full week.

Calculating Pay With Decimal Hours

Gross pay equals decimal hours multiplied by the hourly rate. 8.75 hours × $20.00 = $175.00. Entering 8:45 as 8.45 gives 8.45 × $20.00 = $169.00, which underpays $6.00 for one shift and $30.00 for a 5-shift week.

Rounding Decimal Hours

Payroll rounds decimal hours in 3 common ways:

  • Hundredths: 2 decimal places, such as 7.33 hours. This is the most precise option.
  • Tenths: 6-minute steps, so 1–6 minutes = 0.1 hours.
  • Quarters: 15-minute steps with the 7-minute rule: 1–7 minutes round down and 8–14 minutes round up.

The U.S. Department of Labor allows rounding only when it averages out over time and does not shortchange employees.
