A kilogram is equal to how many pounds?

• A. 2.0
• B. 2.2
• C. 2.5
• D. 3.0

Answer: (B)

Understanding unit conversion between kilograms and pounds is key here. One kilogram equals about 2.2046 pounds, since the pound is defined as 0.45359237 kilograms. In everyday cooking, we round to make quick math easier, so a kilogram is commonly treated as 2.2 pounds. That makes 2.2 the practical value to use. The other numbers are farther off—2.0 underestimates and 2.5 or 3.0 overestimate—so 2.2 pounds is the best rounded answer. If you need more precision, you can use 2.2046.
