Conversion Chart for Military Time

the 24 hour clock image

The military time conversion chart below will help you convert from standard to military time and back.

In military time, or the 24 hour clock, the hours go up to 24 instead of 12, and the words 'am' and 'pm' are no longer needed or used.

Military times are written in the form hh:mm or hh:mm:ss (where h=hour, m=minute and s=seconds)

Often the colon is removed between hours and minutes, so the format is hhmm or hhmm:ss (where h=hour, m=minute, s=seconds)

The hour is always written as a 2 digit number, so any hour below 10 has a zero before it, e.g. 01:23, or 08:37.

On this page, you will also find a quick and easy explanation of how to convert to and from military time, as well as some worksheets for you to try!

Using these resources will help you to:
  • convert between standard and military time;
  • know the formula for converting standard to military time;
  • practice converting from standard to military time.

The Military Time Charts in this section will help you to get your conversion facts right.

Military Time Chart Conversion Formula

The formula below will help you to convert from standard to military time.

Convert from Standard to Military Time

If the hour in standard time is an "am" time:

  • If the hour is 12am, then it changes to 00.

e.g. 12:37am changes to 00:37

Otherwise

  • Military time is the same as Standard time.

Remember to add the preceding zero if the hour is less than 10. Remove the "am" label.


If the hour in standard time is a "pm" time:

  • If the hour is 12pm, then it stays the same.

Otherwise:

  • Add 12 to the number of hours. Remove the "pm" label.

Examples

4:30am = 04:30 (or 0430)   11:45am = 11:45 (or 1145)

12:32am = 00:32 (or 0032)   12:15pm = 12:15 (or 1215)

7:55pm = 19:55 (or 1955)   5:12pm = 17:12 (or 1712)

This formula will help you to convert from Military Time back to Standard Time.

Convert from Military to Standard Time

If the hour in military time is less than 12:

  • if the hour is zero, change it to 12.

Otherwise:

  • Standard time is the same as Military time.

Remember to remove the preceding zero if the hour is less than 10. Add the "am" label.


If the hour in military time is 12 or more:

  • the time is a "pm" time.
  • if the hour is 13 or more, take away 12 from it.

Write down the new hour and minutes and add the "pm" label.

Examples

00:37 = 12:37am   07:42 = 7:42am

12:42 = 12:42pm   20:06 = 8:06pm
