Elapsed Time Calculator

How to calculate elapsed time?

Elapsed time is the difference between a start time and an end time, often requiring unit conversion.

Formula: Duration = (End_Hours - Start_Hours) + (End_Minutes - Start_Minutes)/60

Using the elapsed time calculator: an example

Example: Timing a short race starting at 02:00:15 PM and ending at 02:15:45 PM.

Step-by-step calculation:

• Identify start (14:00:15) and end (14:15:45)
• Subtract seconds: 45 - 15 = 30s
• Subtract minutes: 15 - 0 = 15m
• Total: 15 minutes and 30 seconds
