Understanding 12-Hour and 24-Hour Clock Formats
In order to convert a time from the 12-hour format (AM/PM) to the 24-hour format, it’s important to understand the basic differences between the two systems.
12-Hour Clock Format
- The 12-hour clock divides the day into two segments: AM (from midnight to noon) and PM (from noon to midnight).
- For example, 6:30 PM indicates that it is 6 hours and 30 minutes in the evening.
24-Hour Clock Format
- The 24-hour clock runs from 00:00 (midnight) to 23:59 (one minute before the next midnight).
- Each hour of the day is represented by a number from 0 to 23.
Conversion Process
1. Identify the PM Time: Since 6:30 PM falls in the afternoon/evening, we need to convert it accordingly.
2. Add 12 to the Hour: To convert PM times (except for 12 PM), you add 12 to the hour:
- 6 PM + 12 = 18
3. Retain the Minutes: The minutes remain the same, so:
- 30 minutes stays as 30.
4. Final Conversion: Therefore, 6:30 PM in 24-hour format is:
- 18:30 hours.
Conclusion
Thus, the correct answer is c) 18:30 hours, not option 'C' as stated. Always remember to add 12 to the hour for PM times (except 12 PM) to accurately convert to the 24-hour clock format.
