Convert 205 lbs to kg.
The correct answer and explanation is:
To convert 205 pounds (lbs) to kilograms (kg), use the conversion factor that 1 pound is approximately equal to 0.453592 kilograms. The formula to convert pounds to kilograms is: Weight in kilograms=Weight in pounds×0.453592\text{Weight in kilograms} = \text{Weight in pounds} \times 0.453592
Now, applying the formula: Weight in kilograms=205×0.453592=93.025 kg\text{Weight in kilograms} = 205 \times 0.453592 = 93.025 \, \text{kg}
Therefore, 205 lbs is approximately equal to 93.03 kg.
Explanation:
The process of converting pounds to kilograms relies on a standard conversion factor, which is derived from the relationship between the Imperial system (used for pounds) and the metric system (used for kilograms). The pound is a unit of weight used primarily in the United States, while kilograms are part of the metric system, which is used worldwide for scientific, medical, and general everyday measurements.
The relationship between pounds and kilograms is based on the physical properties of mass. A kilogram is defined as the base unit of mass in the International System of Units (SI), whereas the pound is a unit that originates from the British Imperial system. To bridge the two systems, the conversion factor of 0.453592 kilograms per pound is used. This is a precise value that was established to ensure that mass measurements are consistent across different systems.
The multiplication step converts the weight from pounds to kilograms, ensuring that the result reflects the correct mass in metric units. This conversion is important in various contexts, such as when traveling, trading internationally, or working in fields like medicine, science, and engineering, where the metric system is the standard.
