How to Convert Standard Time to Military Time

Converting standard time to military time (also known as 24-hour time) is a common task in various fields, including military operations, healthcare, and international communications. This process involves transforming the 12-hour clock format to a 24-hour format.

Formula and Components

The conversion process uses the following rules:

  • For AM times:
    • If the hour is 12, subtract 12 (e.g., 12:30 AM becomes 00:30)
    • For all other hours, keep them as is (e.g., 11:45 AM stays 11:45)
  • For PM times:
    • If the hour is 12, keep it as 12 (e.g., 12:15 PM stays 12:15)
    • For all other hours, add 12 (e.g., 1:30 PM becomes 13:30)

Conversion Steps

  1. Identify the hour, minute, and AM/PM indicator from the standard time.
  2. Apply the appropriate conversion rule based on the AM/PM indicator and hour.
  3. Keep the minutes the same.
  4. Format the result as a four-digit number, using leading zeros if necessary.

Example Conversion

Let's convert 3:45 PM to military time:

  1. Identify components: Hour = 3, Minute = 45, Indicator = PM
  2. Since it's PM and not 12, add 12 to the hour: 3 + 12 = 15
  3. Keep minutes as 45
  4. Format as 15:45

Therefore, 3:45 PM in military time is 15:45.
