Metric Conversions worksheet - Free Printable

Let's solve the worksheet step by step.

---

Part 1: Convert the following metric units of length

Use the conversion chart:
- km → m: ×1000
- m → cm: ×100
- cm → mm: ×10
- Reverse: divide by the same factor

---

1) 5 km = ____ m
5 × 1000 = 5000 m

2) 600 cm = ____ m
600 ÷ 100 = 6 m

3) 8 cm = ____ mm
8 × 10 = 80 mm

4) ____ km = 4000 m
4000 ÷ 1000 = 4 km

5) ____ m = 900 cm
900 ÷ 100 = 9 m

6) 120 mm = ____ cm
120 ÷ 10 = 12 cm

7) 7 km = ____ m
7 × 1000 = 7000 m

8) 14 cm = ____ mm
14 × 10 = 140 mm

9) 12 m = ____ cm
12 × 100 = 1200 cm

10) ____ km = 13,000 m
13,000 ÷ 1000 = 13 km

11) ____ cm = 130 mm
130 ÷ 10 = 13 cm

12) 1400 cm = ____ m
1400 ÷ 100 = 14 m

✔ Answers for Part 1:

1) 5000 m
2) 6 m
3) 80 mm
4) 4 km
5) 9 m
6) 12 cm
7) 7000 m
8) 140 mm
9) 1200 cm
10) 13 km
11) 13 cm
12) 14 m

Part 2: Which is the most? Circle the largest amount in each box.

We need to convert all values to the same unit (preferably meters) to compare.

---

Box 1:
- 100 m
- 1 km = 1000 m
- 1000 cm = 10 m
→ Largest: 1 km ✔ (already circled)

---

Box 2:
- 3 km = 3000 m
- 2850 m
- 5000 cm = 50 m
→ Largest: 3 km

✔ Circle: 3 km

---

Box 3:
- 380 cm = 3.8 m
- 4000 mm = 4 m
- 3 m
→ Largest: 4000 mm (4 m)

✔ Circle: 4000 mm

---

Box 4:
- 9020 m
- 20,000 cm = 200 m
- 9 km = 9000 m
→ Compare:
9020 m vs 200 m vs 9000 m → 9020 m is largest

✔ Circle: 9020 m

---

✔ Answers for Part 2:

- Box 1: 1 km ✔ (already done)
- Box 2: 3 km
- Box 3: 4000 mm
- Box 4: 9020 m

---

Part 3: Use >, <, or = to compare amounts

Convert both sides to the same unit and compare.

---

1) 3 km ___ 2000 m
3 km = 3000 m → 3000 > 2000 → >

2) 1000 m ___ 1 km
1 km = 1000 m → =

3) 5 cm ___ 50 mm
5 cm = 50 mm → =

4) 300 m ___ 3 km
3 km = 3000 m → 300 < 3000 → <

5) 7 m ___ 500 cm
7 m = 700 cm → 700 > 500 → >

6) 6 cm ___ 80 mm
6 cm = 60 mm → 60 < 80 → <

7) 30 mm ___ 3 cm
3 cm = 30 mm → =

8) 800 cm ___ 7 m
800 cm = 8 m → 8 > 7 → >

9) 40 cm ___ 4 m
4 m = 400 cm → 40 < 400 → <

10) 5 km ___ 4900 m
5 km = 5000 m → 5000 > 4900 → >
