The Correct Answer and Explanation is:
Let’s go through the conversion of weights from pounds (lb) and ounces (oz) to kilograms (kg). The key to solving these problems is knowing the conversion factor:
1 pound (lb) = 0.453592 kilograms (kg)
1 ounce (oz) = 0.0625 pounds (lb)
✅ Correct Answers:
- 15 lb = 6.8 kg
- 33 lb = 15.0 kg (Already given: 33 × 0.4536 = 14.96 ≈ 15.0 kg)
- 8 lb 4 oz = 3.7 kg
- 4 oz = 0.25 lb → 8.25 lb × 0.4536 = 3.74 kg → 3.7 kg
- 2.68 lb = 1.2 kg
- 2.68 × 0.4536 = 1.22 kg → 1.2 kg
- 31 lb = 14.1 kg
- 31 × 0.4536 = 14.06 kg → 14.1 kg
- 12 lb 12 oz = 5.8 kg
- 12 oz = 0.75 lb → total = 12.75 lb × 0.4536 = 5.78 kg → 5.8 kg
- 32 lb = 14.5 kg
- 32 × 0.4536 = 14.51 kg → 14.5 kg
- 100.4 lb = 45.5 kg
- 100.4 × 0.4536 = 45.53 kg → 45.5 kg
- 71 lb = 32.2 kg
- 71 × 0.4536 = 32.21 kg → 32.2 kg
- 924 lb = 419.2 kg
- 924 × 0.4536 = 419.2 kg
📘 300-Word Explanation:
When converting pounds to kilograms, it’s important to use the correct conversion factor:
1 pound = 0.4536 kilograms (rounded).
This means that to convert any weight in pounds to kilograms, you simply multiply the number of pounds by 0.4536. For example, if you have 15 lb, the calculation is:
15 × 0.4536 = 6.804 kg, which rounds to 6.8 kg (to the nearest tenth).
For weights that include ounces, remember there are 16 ounces in 1 pound. So, to convert ounces to pounds, divide the number of ounces by 16. For instance:
4 oz = 4 ÷ 16 = 0.25 lb
If the total weight is 8 lb 4 oz, then:
8 + 0.25 = 8.25 lb → 8.25 × 0.4536 = 3.74 kg → 3.7 kg
Rounding is important in medical and nursing settings to ensure proper dosing and safe patient care. Most clinical calculations are rounded to the nearest tenth, unless specified otherwise.
Additionally, understanding how to convert these measurements accurately is vital for tasks like medication dosing based on body weight, calculating fluid replacement needs, or determining nutritional requirements.
Being comfortable with unit conversions supports accuracy, reduces errors, and ensures high standards of care in nursing practice. It’s also a common area tested on exams and licensure assessments.
