Metric unit conversion worksheet for weight and volume practice.

Of course! Let’s solve the problems on this worksheet step by step. The worksheet has three main sections:

---

## Section 1: Converting Metric Units – Weight & Volume

You need to convert between kilograms (kg) and grams (g), and liters (L) and milliliters (mL).

Key Conversion Facts:

- 1 kg = 1000 g
- 1 L = 1000 mL

---

Problems 1–12:

1) 1 kg = ___ g
→ 1 × 1000 = 1000 g

2) 2 kg = ___ g
→ 2 × 1000 = 2000 g

3) 3 kg = ___ g
→ 3 × 1000 = 3000 g

4) 4 kg = ___ g
→ 4 × 1000 = 4000 g

5) 5 kg = ___ g
→ 5 × 1000 = 5000 g

6) 6 kg = ___ g
→ 6 × 1000 = 6000 g

7) 1 L = ___ mL
→ 1 × 1000 = 1000 mL

8) 2 L = ___ mL
→ 2 × 1000 = 2000 mL

9) 3 L = ___ mL
→ 3 × 1000 = 3000 mL

10) 4 L = ___ mL
→ 4 × 1000 = 4000 mL

11) 5 L = ___ mL
→ 5 × 1000 = 5000 mL

12) 6 L = ___ mL
→ 6 × 1000 = 6000 mL

✔ All done! These are straightforward conversions using the factor of 1000.

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

You’re given sets of 4 measurements — some in kg/g, some in L/mL — and you must find the largest value in each set.

Let’s convert everything to the same unit for easy comparison.

---

Box 1:

- 1 kg → 1000 g
- 100 g → 100 g
- 500 g → 500 g
- 250 g → 250 g

✔ Largest: 1 kg (1000 g)

---

Box 2:

- 2 L → 2000 mL
- 1200 mL → 1200 mL
- 2100 mL → 2100 mL
- 2200 mL → 2200 mL

✔ Largest: 2200 mL

---

Box 3:

- 600 g → 600 g
- 4 kg → 4000 g
- 3500 g → 3500 g
- 3000 g → 3000 g

✔ Largest: 4 kg (4000 g)

---

Box 4:

- 3 L → 3000 mL
- 3050 mL → 3050 mL
- 3200 mL → 3200 mL
- 3100 mL → 3100 mL

✔ Largest: 3200 mL

---

## Section 3: Use >, <, or = to compare the amounts.

We’ll convert both sides to the same unit and then compare.

---

1) 1 L ___ 50 mL

→ 1 L = 1000 mL → 1000 mL > 50 mL
✔ >

---

2) 2000 mL ___ 1 L

→ 1 L = 1000 mL → 2000 mL > 1000 mL
✔ >

---

3) 1 kg ___ 1000 g

→ 1 kg = 1000 g
✔ =

---

4) 2 kg ___ 700 mL

⚠️ Problem here: You can’t directly compare weight (kg) with volume (mL) unless you know the substance (e.g., water). But since this is a basic metric conversion worksheet, it’s likely a typo — probably meant to be 700 g.

Assuming it’s 700 g (which makes sense contextually):

→ 2 kg = 2000 g → 2000 g > 700 g
✔ >

*(If it really is 700 mL, then the comparison is invalid without density info — but for grade school level, it’s almost certainly a typo.)*

---

5) 1 L ___ 1000 mL

→ 1 L = 1000 mL
✔ =

---

6) 4000 mL ___ 4 L

→ 4 L = 4000 mL
✔ =

---

7) 2000 g ___ 5 kg

→ 5 kg = 5000 g → 2000 g < 5000 g
✔ <

---

8) 2 L ___ 4500 mL

→ 2 L = 2000 mL → 2000 mL < 4500 mL
✔ <

---

9) 3 L ___ 3100 mL

→ 3 L = 3000 mL → 3000 mL < 3100 mL
✔ <

---

10) 2000 mL ___ 3 kg

⚠️ Again, comparing volume and mass. Likely a typo — should be 3000 g or similar.

Assuming it’s 3000 g:

→ 2000 mL (if water) = 2000 g → 2000 g < 3000 g
✔ <

*(If it's truly 3 kg, then again, it’s invalid unless we assume water density — 1 mL water = 1 g, so 2000 mL water = 2 kg → 2 kg < 3 kg → still <)*

So even if we interpret literally (assuming water), 2000 mL ≈ 2 kg < 3 kg → <

✔ <
