Converting metric units of length worksheet with fill-in-the-blank exercises and comparison tasks.

Let's solve the "Converting Metric Units – Length Sheet 3" step by step.

🔢 Metric Conversions (Length):

Remember these key conversions:
- 1 km = 1000 m
- 1 m = 100 cm
- 1 cm = 10 mm

We'll use these to convert between units.

## ✔ Part 1: Fill in the blanks

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

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

We need to convert all values in each box to the same unit (preferably meters), then compare.

---

🟦 Box 1:

- 100 m → 100 m
- 1 km → 1 × 1000 = 1000 m
- 1000 cm → 1000 ÷ 100 = 10 m

✔ Largest: 1 km (already circled)

---

🟨 Box 2:

- 3 km → 3 × 1000 = 3000 m
- 2850 m → 2850 m
- 5000 cm → 5000 ÷ 100 = 50 m

Compare:
3000 m > 2850 m > 50 m

✔ Largest: 3 km

---

🟩 Box 3:

- 380 cm → 380 ÷ 100 = 3.8 m
- 4000 mm → 4000 ÷ 1000 = 4 m (since 1000 mm = 1 m)
- 3 m → 3 m

Compare:
4 m > 3.8 m > 3 m

✔ Largest: 4000 mm

---

🟪 Box 4:

- 9020 m → 9020 m
- 20,000 cm → 20,000 ÷ 100 = 200 m
- 9 km → 9 × 1000 = 9000 m

Compare:
9020 m > 9000 m > 200 m

✔ Largest: 9020 m

---

✔ Final Answers for "Which is the most?" (Circle the largest):

| Box | Largest Amount |
|-----|----------------|
| 1 | 1 km ✔ (already circled) |
| 2 | 3 km |
| 3 | 4000 mm |
| 4 | 9020 m |

---

## ✔ Final Answer Summary:

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: Circle the largest in each box:

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