What is 98 pounds in kilograms?

• A. 44.4 kg
• B. 9.9 kg
• C. 32.6 kg
• D. 62.1 kg

Answer: (A)

Converting pounds to kilograms uses the fact that 1 pound is about 0.4536 kilograms. Multiply the number of pounds by this factor to get kilograms. For 98 pounds, you can use the common quick-approximation 0.453 to get 98 × 0.453 ≈ 44.394 kg, which rounds to 44.4 kg to one decimal place. Using the exact factor 0.45359237 gives about 44.452 kg, which would round to 44.5 kg, but in many practice contexts the simpler 0.453 is used and yields 44.4 kg. So the weight is about 44.4 kilograms. The other options are noticeably farther from the correct magnitude (about 21.8 lb is far lighter, 72 lb is too light in kg, and 137 lb is too heavy in kg).
