Convert units of mass worksheet - Free Printable

To solve these problems, we need to remember the basic conversion between kilograms (kg) and grams (g):

> 1 kilogram = 1000 grams

This means:
- To convert kg to g, multiply by 1000.
- To convert g to kg, divide by 1000 — or think: how many full groups of 1000 grams are there? That’s the kg part, and what’s left is the g part.

Let’s go step by step:

---

1. 5 kg = ? g
→ 5 × 1000 = 5000 g

2. 4 kg = ? g
→ 4 × 1000 = 4000 g

3. 9 kg = ? g
→ 9 × 1000 = 9000 g

4. 4 kg 500 g = ? g
→ 4 kg = 4000 g, plus 500 g → 4000 + 500 = 4500 g

5. 6 kg 75 g = ? g
→ 6 kg = 6000 g, plus 75 g → 6000 + 75 = 6075 g

6. 8 kg 30 g = ? g
→ 8 kg = 8000 g, plus 30 g → 8000 + 30 = 8030 g

7. 8000 g = ? kg
→ 8000 ÷ 1000 = 8 kg

8. 4860 g = ? kg ? g
→ How many full 1000s in 4860? → 4 kg (that’s 4000 g)
→ Leftover: 4860 - 4000 = 860 g
→ So: 4 kg 860 g

9. 7070 g = ? kg ? g
→ 7000 g = 7 kg
→ Leftover: 7070 - 7000 = 70 g
→ So: 7 kg 70 g

10. 6008 g = ? kg ? g
→ 6000 g = 6 kg
→ Leftover: 6008 - 6000 = 8 g
→ So: 6 kg 8 g

Final Answer:
1. 5000
2. 4000
3. 9000
4. 4500
5. 6075
6. 8030
7. 8
8. 4 kg 860 g
9. 7 kg 70 g
10. 6 kg 8 g
