Metric Conversion Worksheet - Free Printable

Let's solve the problems in your image step by step. The worksheet is about converting metric units of weight and volume, and comparing them.

Part 1: Converting Metric Units

We’ll convert each unit using standard metric prefixes:

- Weight (mass):
- 1 kilogram (kg) = 1000 grams (g)
- 1 gram (g) = 1000 milligrams (mg)

- Volume:
- 1 liter (L) = 1000 milliliters (mL)

---

#### Conversions:

1. 3 kg = ___ g
→ 3 × 1000 = 3000 g

2. 4000 g = ___ kg
→ 4000 ÷ 1000 = 4 kg

3. 5 g = ___ mg
→ 5 × 1000 = 5000 mg

4. 6000 mg = ___ g
→ 6000 ÷ 1000 = 6 g

5. 750 mL = ___ L
→ 750 ÷ 1000 = 0.75 L

6. 2 L = ___ mL
→ 2 × 1000 = 2000 mL

7. 9 L = ___ mL
→ 9 × 1000 = 9000 mL

8. 25,000 mg = ___ g
→ 25,000 ÷ 1000 = 25 g

9. 11 kg = ___ g
→ 11 × 1000 = 11,000 g

10. 1500 mL = ___ L
→ 1500 ÷ 1000 = 1.5 L

Part 2: Circle the Largest Amount in Each Row

We need to convert all values to the same unit and compare.

#### Row 1:
- 100 g
- 400 g
- 3 kg → 3000 g
- 5000 mg → 5 g
- 2000 mL → 2 L (but this is volume, not mass — likely a typo? Wait: maybe it’s meant to be grams or something else?)

Wait — 2000 mL is volume, while others are mass (grams). This might be an error, but let's assume it's a mix-up and they meant 2000 g or perhaps it's a separate category?

But looking closely:
The row has:
- 100 g
- 400 g
- 3 kg
- 5000 mg
- 2000 mL

But mL is volume, not mass. So unless it's referring to water (where 1 mL ≈ 1 g), we can assume 1 mL ≈ 1 g for water.

So:
- 2000 mL ≈ 2000 g (if water)

Now convert all to grams:
- 100 g
- 400 g
- 3 kg = 3000 g
- 5000 mg = 5 g
- 2000 mL ≈ 2000 g

So largest is 3000 g (3 kg)

✔ Answer: 3 kg

#### Row 2:
- 800 mg
- 800 mL
- 300 g
- 5000 mL

Again, mix of mass and volume. Assume mL = g (for water):

Convert all to grams:
- 800 mg = 0.8 g
- 800 mL ≈ 800 g
- 300 g = 300 g
- 5000 mL ≈ 5000 g

So largest is 5000 mL ≈ 5000 g

✔ Answer: 5000 mL

Part 3: Compare Using >, <, or =

We need to convert both sides to the same unit and compare.

1. 300 g ___ 3000 mg
→ 300 g = 300,000 mg
→ 300,000 mg > 3000 mg
✔ >

2. 5 L ___ 500 mL
→ 5 L = 5000 mL
→ 5000 mL > 500 mL
✔ >

3. 2 kg ___ 2000 g
→ 2 kg = 2000 g
✔ =

4. 2,400 mL ___ 2.4 L
→ 2,400 mL = 2.4 L
✔ =

5. 3.5 kg ___ 3500 g
→ 3.5 kg = 3500 g
✔ =

6. 1000 mL ___ 1 L
→ 1000 mL = 1 L
✔ =

7. 7 kg ___ 7000 g
→ 7 kg = 7000 g
✔ =

8. 7200 g ___ 8 kg
→ 7200 g = 7.2 kg
→ 7.2 kg < 8 kg
✔ <

9. 3000 g ___ 3000 mL
→ 3000 g = 3000 mL (assuming water)
✔ =

10. 8000 mL ___ 10 L
→ 8000 mL = 8 L
→ 8 L < 10 L
✔ <

11. 120 L ___ 1 L
→ 120 L > 1 L
✔ >

12. 500 mL ___ 500 g
→ Assuming water: 500 mL ≈ 500 g
✔ =
