Understanding Military Time Notation
Military time, also known as the 24-hour clock, is a timekeeping system that differs from the traditional 12-hour clock. It is widely used in military organizations, aviation, and other fields that require precise timekeeping. In military time, the day is divided into 24 hours, starting from midnight (00:00) and ending at midnight (24:00). Each hour is further divided into 60 minutes, similar to the 12-hour clock.
Key Facts
- Military time notation is based on a 24-hour clock, where the time is written in the form hhmm. The hours range from 0 to 23, representing the full hours that have passed since midnight, and the minutes range from 00 to 59.
- To convert military time to the 12-hour standard time format, you need to determine whether the hour is greater than 12. If it is, subtract 12 from the given hour to get the PM time.
- In the case of 16:45 military time, the hour 16 is greater than 12. Subtracting 12 from 16 gives us 4. Therefore, 16:45 military time is equivalent to 4:45 PM in the 12-hour standard time format.
Converting Military Time to Standard Time
To convert military time to the standard 12-hour format, follow these steps:
-
Identify the Hour
Determine the hour component of the military time. In the case of 16:45, the hour is 16.
-
Check if the Hour is Greater Than 12
If the hour is greater than 12, it indicates that the time is in the afternoon or evening. In this case, 16 is greater than 12.
-
Subtract 12 from the Hour
To convert to the 12-hour format, subtract 12 from the military hour. In this case, 16 – 12 = 4.
-
Add “PM” to the Time
Since the hour is greater than 12, it represents the afternoon or evening. Therefore, add “PM” to the end of the time.
Example: Converting 16:45 Military Time to Standard Time
Using the steps above, let’s convert 16:45 military time to standard time:
-
Identify the Hour
The hour component of 16:45 is 16.
-
Check if the Hour is Greater Than 12
16 is greater than 12, indicating that the time is in the afternoon or evening.
-
Subtract 12 from the Hour
Subtracting 12 from 16 gives us 4.
-
Add “PM” to the Time
Since the hour is greater than 12, we add “PM” to the end of the time.
Therefore, 16:45 military time is equivalent to 4:45 PM in the standard 12-hour format.
Conclusion
Military time provides a clear and concise way of expressing time, eliminating any ambiguity between morning and afternoon time values. Understanding how to convert between military time and standard time is essential for effective communication in various professional settings.
