## 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 21:51 converted to 09:51 PM ?

1. Step One: To convert 21:51 (twenty-one fifty-one) to 12-hour, firstly, we didn't convert the minutes, we leave it. In our case it will be ( :51 fifty-one ). 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 21 (nine), so we subtract 12 from 21 then add PM like ( 21 - 12 ). It will be 9 PM. (9 PM means 9 in the noon).

The final result is:09:51 PM ( In words: nine fifty-one in the noon ). Look at the chart below.
