Formulas

Time Formulas

Here are the key formulas for time calculations:

Calculation Formulas:
  • Total Hours = (End Time - Start Time) in hours
  • Total Minutes = Total Hours × 60
  • Total Seconds = Total Hours × 3600
Examples

Practical Examples

Example 1 Basic Time Difference

Calculate the hours between 9:00 AM and 2:00 PM.

Hours = 14:00 - 9:00 = 5 hours

Example 2 Minutes Calculation

Calculate the minutes between 1:30 PM and 2:45 PM.

Hours = 2.75 - 1.5 = 1.25 hours

Minutes = 1.25 × 60 = 75 minutes

Example 3 Complex Time Calculation

Calculate the time span between 11:30 PM and 2:15 AM (next day).

Hours = 26.25 - 23.5 = 2.75 hours

Minutes = 2.75 × 60 = 165 minutes

Seconds = 2.75 × 3600 = 9,900 seconds
