Introduction

Metric measurements are a crucial part of our daily lives, and being able to convert between different units is essential for various applications, including science, engineering, and everyday calculations. In this article, we will explore the process of converting metric measurements by multiplying or dividing by a power of 10. We will cover four different scenarios, each with a unique set of measurements and conversion factors.

Converting Millimeters to Centimeters

1. $5.4 \, \text{m} = \qquad \text{cm}$

To convert millimeters to centimeters, we need to divide the measurement by 10, since there are 10 millimeters in 1 centimeter. However, in this case, we are given a measurement in meters, so we need to convert it to millimeters first.

1 meter is equal to 1000 millimeters, so we can convert 5.4 meters to millimeters by multiplying it by 1000.

$5.4 \, \text{m} \times 1000 = 5400 \, \text{mm}$

Now that we have the measurement in millimeters, we can convert it to centimeters by dividing by 10.

$5400 \, \text{mm} \div 10 = 540 \, \text{cm}$

Therefore, $5.4 \, \text{m} = 540 \, \text{cm}$ .

2. $2.7 \, \text{km} = \qquad \text{m}$

To convert kilometers to meters, we need to multiply the measurement by 1000, since there are 1000 meters in 1 kilometer.

$2.7 \, \text{km} \times 1000 = 2700 \, \text{m}$

Therefore, $2.7 \, \text{km} = 2700 \, \text{m}$ .

3. $0.02 \, \text{km} = \qquad \text{cm}$

To convert kilometers to centimeters, we need to multiply the measurement by 100,000, since there are 100,000 centimeters in 1 kilometer.

$0.02 \, \text{km} \times 100,000 = 2000 \, \text{cm}$

Therefore, $0.02 \, \text{km} = 2000 \, \text{cm}$ .

4. $0.025 \, \text{km} = \qquad \text{mm}$

To convert kilometers to millimeters, we need to multiply the measurement by 1,000,000, since there are 1,000,000 millimeters in 1 kilometer.

$0.025 \, \text{km} \times 1,000,000 = 25,000 \, \text{mm}$

Therefore, $0.025 \, \text{km} = 25,000 \, \text{mm}$ .

Conclusion

Converting metric measurements by multiplying or dividing by a power of 10 is a simple yet essential skill to have. By understanding the relationships between different units, we can easily convert between them. In this article, we covered four different scenarios, each with a unique set of measurements and conversion factors. We hope that this guide has been helpful in understanding how to convert metric measurements and has provided you with the confidence to tackle more complex calculations in the future.
