24 hour clock worksheet - Free Printable

To solve this matching task, we need to convert each time from the 12-hour clock format (with am/pm) to the 24-hour clock format.

Here’s how it works:

- For times from 12:00 am to 11:59 am, the 24-hour time is the same — just remove “am” and write it as HH:00 or HH:MM.
- Example: 6 am → 06:00h
- Example: 11 am → 11:00h

- For times from 12:00 pm to 11:59 pm, add 12 to the hour, then remove “pm”.
- Example: 4:30 pm → 4 + 12 = 16 → 16:30h
- Example: 5 pm → 5 + 12 = 17 → 17:00h
- Example: 6:30 pm → 6 + 12 = 18 → 18:30h
- Example: 10 pm → 10 + 12 = 22 → 22:00h

Now let’s match each one:

1. 6 am → 06:00h → matches with option 4 on the right
2. 4:30 pm → 16:30h → matches with option 5 on the right
3. 11 am → 11:00h → matches with option 2 on the right
4. 10 pm → 22:00h → matches with option 6 on the right
5. 6:30 pm → 18:30h → matches with option 3 on the right
6. 5 pm → 17:00h → matches with option 1 on the right

Let’s double-check:

- 6 am → 06:00h ✔
- 4:30 pm → 16:30h ✔
- 11 am → 11:00h ✔
- 10 pm → 22:00h ✔
- 6:30 pm → 18:30h ✔
- 5 pm → 17:00h ✔

All conversions are correct.

Final Answer:
1 → 4
2 → 5
3 → 2
4 → 6
5 → 3
6 → 1
