24-hour to 12-hour conversion


Our "Military time converter" is the perfect tool to convert time from a 24-hour system to a 12-hour system. Try it above. Enter both the "Hours" and the "Minutes" boxs in the form, then click "convert to 12-hour". After that, you can see the result.

The 24-hour system (it's called the Military system) is larger than 12:00. And it starts at 00:00 and ends at 23:00. 00:00 means 12:00 midnight, and 23:00 means 11:00 PM. (Note: 24:00 and 00:00 are the same time).



How was 18:40 converted to 06:40 PM ?


1. Step One: To convert 18:40 (eighteen forty) to 12-hour, firstly, we didn't convert the minutes, we leave it. In our case it will be ( :40 forty ). and we just convert the hours.


2. Step Two: If the number of hours on military time (24-hour system) that we need to convert it, is less than 12:00, it will be the same on regular time (12-hour system).

In our case, It's 18 (six), so we subtract 12 from 18 then add PM like ( 18 - 12 ). It will be 6 PM. (6 PM means 6 in the noon).

The final result is:06:40 PM ( In words: six forty in the noon ). Look at the chart below.
