Let's solve this step by step. The worksheet is about
converting metric units of length and comparing them. We'll go through each section.

🔹 Part 1: Converting Metric Units
We use the following conversions:
- 1 km = 1000 m
- 1 m = 100 cm
- 1 cm = 10 mm
####
✔ Answers:
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 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:
1 km ✔️
---
Box 2:
- 3 km = 3000 m
- 2850 m
- 5000 cm = 50 m
Compare:
- 3000 m
- 2850 m
- 50 m
→ Largest:
3 km
✔ Circle:
3 km
---
Box 3:
- 380 cm = 3.8 m
- 4000 mm = 4 m
- 3 m
→ Largest:
4000 mm (since 4 m > 3.8 m and 3 m)
✔ Circle:
4000 mm
---
Box 4:
- 9020 m
- 20,000 cm = 200 m
- 9 km = 9000 m
Compare:
- 9020 m
- 200 m
- 9000 m
→ Largest:
9020 m
✔ Circle:
9020 m

🔹 Part 3: Compare using >, <, or =
We convert both sides to the same unit.
---
1)
1200 m ___ 1 km
→ 1 km = 1000 m
→ 1200 > 1000 →
>
2)
620 cm ___ 7 m
→ 7 m = 700 cm
→ 620 < 700 →
<
3)
8 m ___ 750 cm
→ 8 m = 800 cm
→ 800 > 750 →
>
4)
82 mm ___ 7 cm
→ 7 cm = 70 mm
→ 82 > 70 →
>
5)
45 mm ___ 5 cm
→ 5 cm = 50 mm
→ 45 < 50 →
<
6)
1300 cm ___ 13 m
→ 13 m = 1300 cm →
=
7)
900 m ___ 9 km
→ 9 km = 9000 m
→ 900 < 9000 →
<
8)
3½ km ___ 3080 m
→ 3½ km = 3.5 km = 3500 m
→ 3500 > 3080 →
>
9)
12 cm ___ 120 mm
→ 12 cm = 120 mm →
=
10)
425 cm ___ 4½ m
→ 4½ m = 4.5 m = 450 cm
→ 425 < 450 →
<
