175 lbs kg (Note: 2.2 lb-1kg)
The Correct Answer and Explanation is :
To convert 175 pounds to kilograms, we use the conversion factor where 1 kilogram is equal to 2.2 pounds. Therefore, we can set up the conversion as follows:
[
\text{kilograms} = \frac{\text{pounds}}{2.2}
]
Substitute 175 pounds into the equation:
[
\text{kilograms} = \frac{175}{2.2} = 79.545 \text{ kg}
]
Thus, 175 pounds is approximately equal to 79.55 kilograms.
Explanation of Conversion:
The process of converting pounds to kilograms involves dividing the given weight in pounds by the conversion factor of 2.2 pounds per kilogram. This conversion factor is based on the fact that 1 kilogram is equivalent to 2.2 pounds. It means that if we have a weight in pounds, we can divide it by 2.2 to get the equivalent weight in kilograms.
This relationship is a simple ratio where the unit “pounds” is scaled down by a factor of 2.2 to arrive at the corresponding weight in kilograms. Understanding this is important because kilograms are the standard unit of mass used in most countries around the world, while pounds are commonly used in the United States and a few other places.
This unit conversion is often necessary when traveling internationally, working with scientific data, or when discussing health and fitness metrics. For example, many countries use the metric system, which relies on kilograms for measuring body weight, whereas the U.S. typically uses pounds.
By using the conversion factor (1 kilogram = 2.2 pounds), you can easily switch between these units without much complexity. The key to mastering unit conversions is memorizing or knowing the correct conversion factors and applying them appropriately in calculations, ensuring accuracy in both everyday scenarios and scientific calculations.
