How do you convert 175 lbs to kg?
The Correct Answer and Explanation is:
To convert pounds (lbs) to kilograms (kg), you can use the conversion factor where 1 pound is approximately equal to 0.453592 kilograms. Therefore, to convert 175 pounds to kilograms, you multiply the number of pounds by this conversion factor.
The formula to perform the conversion is as follows:
[
\text{kilograms} = \text{pounds} \times 0.453592
]
Applying this formula to the given weight:
[
\text{kilograms} = 175 \, \text{lbs} \times 0.453592 \, \text{kg/lb}
]
Calculating this gives:
[
\text{kilograms} \approx 175 \times 0.453592 \approx 79.832 \, \text{kg}
]
Thus, 175 pounds is approximately 79.83 kilograms when rounded to two decimal places.
Explanation
Understanding the conversion from pounds to kilograms is essential, particularly in fields like healthcare, fitness, and nutrition, where precise weight measurements are crucial. The pound is a unit commonly used in the United States and some other countries, while the kilogram is part of the metric system, widely used internationally. As such, converting between these units can often be necessary.
When performing such conversions, it is important to remember that the conversion factor is derived from the definition of these units. One pound is defined as exactly 0.45359237 kilograms. In many practical applications, this value is rounded to 0.453592 for convenience.
In practical scenarios, such as when measuring body weight or when calculating dosage for medications based on body weight, using the correct conversion ensures accuracy. Furthermore, many scales are now designed to provide measurements in both pounds and kilograms, allowing for easy conversions. In summary, converting pounds to kilograms is a straightforward process that relies on a fixed conversion factor, enabling effective communication of weight measurements across different systems.
