Introduction

In everyday life, we often encounter various units of measurement, and converting between them is a crucial skill to possess. One such conversion is from pounds (lb) to kilograms (kg), which is a common task in various fields, including science, engineering, and even cooking. In this article, we will explore how to convert 4 pounds to kilograms, using a simple yet essential math concept.

Understanding the Conversion Factor

Before we dive into the conversion, it's essential to understand the conversion factor between pounds and kilograms. The given hint states that 1 lb≈0.454 kg1 \, \text{lb} \approx 0.454 \, \text{kg}. This means that 1 pound is approximately equal to 0.454 kilograms. We can use this conversion factor to convert any amount of pounds to kilograms.

Converting 4 Pounds to Kilograms

Now that we have the conversion factor, let's convert 4 pounds to kilograms. We can use the following formula:

kg=lb×0.454 kg1 lb\text{kg} = \text{lb} \times \frac{0.454 \, \text{kg}}{1 \, \text{lb}}

Substituting the given value of 4 pounds, we get:

kg=4 lb×0.454 kg1 lb\text{kg} = 4 \, \text{lb} \times \frac{0.454 \, \text{kg}}{1 \, \text{lb}}

Simplifying the expression, we get:

kg=1.816 kg\text{kg} = 1.816 \, \text{kg}

Rounding the Answer to the Nearest Tenth

The problem asks us to round the answer to the nearest tenth. To do this, we look at the hundredth place, which is 6 in this case. Since 6 is greater than or equal to 5, we round up the tenth place to 2. Therefore, the final answer is:

kg=1.8 kg\text{kg} = 1.8 \, \text{kg}

Conclusion

In conclusion, converting 4 pounds to kilograms is a simple yet essential math concept that can be achieved using a conversion factor. By understanding the conversion factor between pounds and kilograms, we can easily convert any amount of pounds to kilograms. In this article, we used the conversion factor to convert 4 pounds to kilograms and rounded the answer to the nearest tenth.
