How many pounds are there in one kilogram?

• A. 0.45 pounds
• B. 2.2 pounds
• C. 1.0 pounds
• D. 4.4 pounds

Answer: (B)

Understanding unit conversions between kilograms and pounds. A kilogram is part of the metric system, while a pound is used in the US customary system. The exact conversion is 1 kilogram = 2.2046 pounds, so we round to about 2.2 pounds for practical use. That makes one kilogram weigh a little over two pounds, which is why the option stating roughly 2.2 pounds is the best match. The other values don’t fit because 0.45 pounds is about 0.204 kilograms, far less than 1 kilogram; 1.0 pound is about 0.45 kilograms; and 4.4 pounds is about 2 kilograms.
