Metric Conversion Worksheet - Free Printable

Let’s go step by step to solve each part of the worksheet.

Part 1: Fill in the blanks (Converting metric units)

We need to remember these basic conversions:
- 1 cm = 10 mm
- 1 m = 100 cm
- 1 km = 1000 m

Now let’s solve each one:

1) ___ mm = 1 cm → Since 1 cm = 10 mm, answer is 10

2) 1 km = ___ m → 1 km = 1000 m, so 1000

3) 1 m = ___ cm → 1 m = 100 cm, so 100

4) 3 cm = ___ mm → 3 × 10 = 30

5) 4 km = ___ m → 4 × 1000 = 4000

6) ___ mm = 5 cm → 5 × 10 = 50

7) ___ cm = 2 m → 2 × 100 = 200

8) ___ km = 2000 m → 2000 ÷ 1000 = 2

9) 6 m = ___ cm → 6 × 100 = 600

10) ___ mm = 8 cm → 8 × 10 = 80

11) ___ m = 800 cm → 800 ÷ 100 = 8

12) 7 m = ___ cm → 7 × 100 = 700

✔ All done for Part 1!

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

We’ll convert everything to the same unit (meters) to compare easily.

Box 1:
- 1 m
- 1 km = 1000 m ← biggest
- 1 cm = 0.01 m
→ So circle 1 km (already circled in image — correct!)

Box 2:
- 1 km = 1000 m
- 2000 m ← biggest
- 3000 cm = 30 m
→ Circle 2000 m

Box 3:
- 2 m
- 400 cm = 4 m ← biggest
- 700 mm = 0.7 m
→ Circle 400 cm

Box 4:
- 5 km = 5000 m ← biggest
- 6000 cm = 60 m
- 4000 m
→ Circle 5 km

✔ Done with Part 2!

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

Again, convert to same unit (we’ll use meters unless easier otherwise).

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

2) 1000 m vs 1 km
→ 1 km = 1000 m → equal → =

3) 5 cm vs 50 mm
→ 5 cm = 50 mm → equal → =

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

5) 7 m vs 500 cm
→ 500 cm = 5 m → 7 > 5 → >

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

7) 30 mm vs 3 cm
→ 3 cm = 30 mm → equal → =

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

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

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

✔ All comparisons done!
