According to the material, 1 pound is equal to approximately how many kilograms?

• A. 2.2 kilograms
• B. 0.45 kilograms
• C. 0.25 kilograms
• D. 1.0 kilograms

Answer: (B)

Converting pounds to kilograms relies on the rough but handy rule that 1 kilogram is about 2.2 pounds. So, 1 pound is the reciprocal of that: 1/2.2, which is roughly 0.45 kilograms. This reflects why 1 pound is a bit less than half a kilogram—the kilogram is a little more than twice as heavy as a pound. The other options don’t fit this relationship: 2.2 kilograms would be almost 5 pounds, 0.25 kilograms is about 0.55 pounds, and 1.0 kilogram is about 2.2 pounds. Therefore, 1 pound ≈ 0.45 kilograms.
