Convert between Kilograms and Grams Worksheets - Free Printable

Problem Overview:

The task involves converting measurements between kilograms (kg) and grams (g). The key relationship to remember is:
- 1 kilogram (kg) = 1000 grams (g)

This means:
- To convert grams to kilograms, divide by 1000.
- To convert kilograms to grams, multiply by 1000.

Let's solve each part step by step.

---

Part 1: Convert each measure from grams to kilograms

#### 1) \( 3,500 \, \text{g} \)
To convert grams to kilograms, divide by 1000:
\[
3,500 \, \text{g} \div 1000 = 3.5 \, \text{kg}
\]

#### 2) \( 2,004 \, \text{g} \)
\[
2,004 \, \text{g} \div 1000 = 2.004 \, \text{kg}
\]

#### 3) \( 81,620 \, \text{g} \)
\[
81,620 \, \text{g} \div 1000 = 81.62 \, \text{kg}
\]

#### 4) \( 11,920 \, \text{g} \)
\[
11,920 \, \text{g} \div 1000 = 11.92 \, \text{kg}
\]

#### 5) \( 4,000 \, \text{g} \)
\[
4,000 \, \text{g} \div 1000 = 4.0 \, \text{kg}
\]

#### 6) \( 65,370 \, \text{g} \)
\[
65,370 \, \text{g} \div 1000 = 65.37 \, \text{kg}
\]

#### 7) \( 75,960 \, \text{g} \)
\[
75,960 \, \text{g} \div 1000 = 75.96 \, \text{kg}
\]

#### 8) \( 9,000 \, \text{g} \)
\[
9,000 \, \text{g} \div 1000 = 9.0 \, \text{kg}
\]

Part 2: Convert each measure from kilograms to grams

#### 1) \( 3 \, \text{kg} \)
To convert kilograms to grams, multiply by 1000:
\[
3 \, \text{kg} \times 1000 = 3,000 \, \text{g}
\]

#### 2) \( 11.85 \, \text{kg} \)
\[
11.85 \, \text{kg} \times 1000 = 11,850 \, \text{g}
\]

#### 3) \( 28.554 \, \text{kg} \)
\[
28.554 \, \text{kg} \times 1000 = 28,554 \, \text{g}
\]

#### 4) \( 4.76 \, \text{kg} \)
\[
4.76 \, \text{kg} \times 1000 = 4,760 \, \text{g}
\]

#### 5) \( 57 \, \text{kg} \)
\[
57 \, \text{kg} \times 1000 = 57,000 \, \text{g}
\]

#### 6) \( 90.71 \, \text{kg} \)
\[
90.71 \, \text{kg} \times 1000 = 90,710 \, \text{g}
\]

#### 7) \( 8.32 \, \text{kg} \)
\[
8.32 \, \text{kg} \times 1000 = 8,320 \, \text{g}
\]

#### 8) \( 61 \, \text{kg} \)
\[
61 \, \text{kg} \times 1000 = 61,000 \, \text{g}
\]
