Question

1 kilogram is about ____.
a 2.2 tons
b 2.2 pounds
c 2.2 ounces
d 0.22 ton

Explanation:

Step1: Recall unit conversion

We know the conversion factor: 1 kilogram ($kg$) is approximately equal to 2.2 pounds ($lb$). Let's analyze each option:

• Option A: 1 ton = 1000 kg, so 2.2 tons is much larger than 1 kg, so A is wrong.
• Option B: As per the conversion, 1 kg ≈ 2.2 pounds, so B is correct.
• Option C: 1 pound = 16 ounces, so 2.2 ounces is much smaller than 1 kg (since 1 kg ≈ 2.2 pounds = 2.2×16 = 35.2 ounces), so C is wrong.
• Option D: 0.22 ton = 0.22×1000 = 220 kg, which is larger than 1 kg, so D is wrong.

Answer:

B. 2.2 pounds
