Understanding Time Units
Time calculations involve different units working together:
- 1 hour = 60 minutes
- 1 minute = 60 seconds
- 12-hour format uses AM/PM
- 24-hour format runs from 00:00 to 23:59
Tips for Accurate Calculations
- Double-check your input format (12-hour vs 24-hour)
- Consider AM/PM when using 12-hour format
- Use appropriate units for your calculation
- Remember that time calculations wrap around (e.g., 23:59 + 1 minute = 00:00). For longer durations, try our Time Duration Calculator
