Quiz & Worksheet - SI Standards of Measurement | Study.com - Free Printable

Let's solve each problem on the Measuring Units Worksheet step by step. We'll convert between kilometers (km), meters (m), centimeters (cm), and millimeters (mm) using standard metric conversions:

Metric Conversion Facts:

- 1 km = 1,000 m
- 1 m = 100 cm
- 1 cm = 10 mm
- 1 m = 1,000 mm

Solutions:

#### 1 a. 7 km = ________ m
7 km × 1,000 = 7,000 m

#### 1 b. 1 cm = ________ mm
1 cm × 10 = 10 mm

#### 2 a. 10 m = ________ cm
10 m × 100 = 1,000 cm

#### 2 b. 200 cm = ________ m
200 cm ÷ 100 = 2 m

#### 3 a. 6,000 m = ________ km
6,000 m ÷ 1,000 = 6 km

#### 3 b. 3,000 m = ________ km
3,000 m ÷ 1,000 = 3 km

#### 4 a. 2,000 m = ________ km
2,000 m ÷ 1,000 = 2 km

#### 4 b. 900 cm = ________ m
900 cm ÷ 100 = 9 m

#### 5 a. 60 mm = ________ cm
60 mm ÷ 10 = 6 cm

#### 5 b. 700 cm = ________ m
700 cm ÷ 100 = 7 m

#### 6 a. 90 mm = ________ cm
90 mm ÷ 10 = 9 cm

#### 6 b. 9,000 m = ________ km
9,000 m ÷ 1,000 = 9 km

#### 7 a. 4,000 m = ________ km
4,000 m ÷ 1,000 = 4 km

#### 7 b. 5,000 m = ________ km
5,000 m ÷ 1,000 = 5 km

#### 8 a. 8,000 m = ________ km
8,000 m ÷ 1,000 = 8 km

#### 8 b. 3 cm = ________ mm
3 cm × 10 = 30 mm

#### 9 a. 7 cm = ________ mm
7 cm × 10 = 70 mm

#### 9 b. 300 cm = ________ m
300 cm ÷ 100 = 3 m

#### 10 a. 20 mm = ________ cm
20 mm ÷ 10 = 2 cm

#### 10 b. 100 mm = ________ cm
100 mm ÷ 10 = 10 cm

🔍 Explanation Summary:

- When converting larger units to smaller units, multiply.
- Example: km → m → ×1,000
- Example: m → cm → ×100
- Example: cm → mm → ×10
- When converting smaller units to larger units, divide.
- Example: mm → cm → ÷10
- Example: cm → m → ÷100
- Example: m → km → ÷1,000

This worksheet reinforces understanding of the metric system and unit conversion in the decimal-based measurement system.
