How many kilograms are in 1 pound?

0.35 kg
0.45 kg
0.55 kg
0.65 kg

The correct answer is: 0.45 kg

To determine how many kilograms are in one pound, it’s essential to understand the conversion factor between pounds and kilograms. One pound is approximately equal to 0.453592 kilograms. When rounded, this value is commonly approximated as 0.45 kg for ease of calculation in various contexts. The choice reflecting this accurate conversion is the second option, which correctly identifies that 1 pound is approximately 0.45 kilograms. This conversion is based on a well-established relationship in measurement systems, where the pound represents a unit of mass commonly used in the United States, while kilogram is the standard unit in the metric system. This provides useful context when converting between imperial and metric systems, highlighting the importance of knowing these conversion factors, especially in fields such as science, engineering, and education, where precise measurements are often required.
