24 Hour Clock Conversion Worksheets - Free Printable

Let's solve this step-by-step. The worksheet has three parts:

---

Part 1: Convert am/pm times to 24-hour clock format

Rules:
- For am times:
- If the time is 12:xx am, it becomes 00:xx.
- Otherwise, keep the hour as-is (e.g., 5:16 am → 05:16).
- For pm times:
- If the time is 12:xx pm, it stays 12:xx.
- Otherwise, add 12 to the hour (e.g., 1:24 pm → 13:24).

#### Solutions:

1) 1:24 pm = 13:24
2) 2:56 am = 02:56
3) 7:45 pm = 19:45
4) 5:16 am = 05:16
5) 3:56 pm = 15:56
6) 12:25 pm = 12:25
7) 11:27 pm = 23:27
8) 8:13 pm = 20:13
9) 12:42 am = 00:42

Part 2: Convert 24-hour clock times to am/pm format

Rules:
- If the hour is 00, it’s 12:xx am.
- If the hour is 12, it’s 12:xx pm.
- If the hour is 1–11, it’s xx:xx am.
- If the hour is 13–23, subtract 12 and write xx:xx pm.

#### Solutions:

1) 13:41 = 1:41 pm
2) 17:50 = 5:50 pm
3) 04:32 = 4:32 am
4) 12:36 = 12:36 pm
5) 23:25 = 11:25 pm
6) 08:53 = 8:53 am
7) 00:51 = 12:51 am
8) 19:08 = 7:08 pm
9) 15:39 = 3:39 pm

Part 3: Read analog clocks and write 24-hour time

We need to read each clock, determine the time (including am/pm), then convert to 24-hour format.

Let’s go one by one:

---

#### Clock 1:
- Hour hand between 3 and 4 → 3
- Minute hand on 7 → 7×5 = 35 minutes
- Label says pm
- Time: 3:35 pm → 15:35

#### Clock 2:
- Hour hand between 10 and 11 → 10
- Minute hand on 8 → 8×5 = 40 minutes
- Label says am
- Time: 10:40 am → 10:40

#### Clock 3:
- Hour hand between 7 and 8 → 7
- Minute hand on 5 → 5×5 = 25 minutes
- Label says pm
- Time: 7:25 pm → 19:25

#### Clock 4:
- Hour hand at 3 → 3
- Minute hand at 12 → 0 minutes
- Label says am
- Time: 3:00 am → 03:00

#### Clock 5:
- Hour hand between 9 and 10 → 9
- Minute hand on 1 → 1×5 = 5 minutes
- Label says am
- Time: 9:05 am → 09:05

#### Clock 6:
- Hour hand between 7 and 8 → 7
- Minute hand on 4 → 4×5 = 20 minutes
- Label says pm
- Time: 7:20 pm → 19:20

#### Clock 7:
- Hour hand between 8 and 9 → 8
- Minute hand on 2 → 2×5 = 10 minutes
- Label says pm
- Time: 8:10 pm → 20:10

#### Clock 8:
- Hour hand between 3 and 4 → 3
- Minute hand on 6 → 6×5 = 30 minutes
- Label says pm
- Time: 3:30 pm → 15:30
