Convert the following to the indicated weight. 1. 142 lb. = _ kg 2. 9.8 T = t 3. 150 oz = kg 4. 21 lb. = kg 5. 900 kg = lb. 6. 43 lb. = g 7. 19 000 lb. = T 8. 18 lb. 8 oz = oz 9. 50 lb. 40 oz = kg 10. 25.5 oz = _ g
The Correct Answer and Explanation is:
Correct Answers:
- 142 lb = 64.41 kg
- 9.8 T = 8.89 t
- 150 oz = 4.25 kg
- 21 lb = 9.53 kg
- 900 kg = 1984.16 lb
- 43 lb = 19504 g
- 19,000 lb = 9.5 T
- 18 lb 8 oz = 296 oz
- 50 lb 40 oz = 28.12 kg
- 25.5 oz = 723 g
Explanation:
Weight conversions follow standard conversion factors among metric and imperial units. To solve each problem, a direct multiplication or division using known equivalencies is applied:
- 1 pound (lb) = 0.4536 kilograms (kg)
- 1 ounce (oz) = 28.35 grams (g)
- 1 ton (T) (imperial) = 0.907 metric tons (t)
- 1 kilogram (kg) = 2.2046 pounds (lb)
- 1 pound (lb) = 16 ounces (oz)
For instance, in question 1, the conversion of 142 pounds to kilograms is accomplished by multiplying by 0.4536. This yields approximately 64.41 kg. Similarly, in question 3, converting ounces to kilograms involves multiplying the ounce value by 28.35 to get grams, then dividing by 1000 to get kilograms.
Question 8 requires adding ounces to pounds. Since 1 pound is 16 ounces, 18 pounds and 8 ounces equals 18 × 16 + 8 = 296 ounces.
In question 9, the total weight in ounces is calculated as 50 × 16 + 40 = 840 ounces. This value is converted to grams by multiplying by 28.35, and the result is converted to kilograms by dividing by 1000, giving approximately 28.12 kg.
Each question uses a different conversion depending on the units involved, and accuracy is maintained by retaining standard decimal approximations up to two decimal places.
