How to convert 13:40 from 24-Hour Time to 12-Hour Standard Time

It is easy to convert from 24-hour time to 12-hour time once you know a few tricks. The primary difference between the two is that the hours in a 24 hour clock go all the way up to 23 (from 0 to 23). In a 12-hour clock, the hour resets to 1 after noon (midday). Follow the steps below to convert 13:40 to 12-hour time.

  1. First, determine whether or not 13 is greater than 12 (recall that this is one of the distinctions of the 12-hour clock, there are no hours "greater" than 12 on it)
  2. The hour 13 is higher than twelve, so we need to subtract 12 from 13 to get our "PM" hour: 13 - 12 = 1
  3. Now add "PM" to the end of the time: 1:40 PM
