What is the equivalent of 2.2 lbs in kilograms?

To convert pounds to kilograms, you can use the conversion factor where 1 pound equals approximately 0.4536 kilograms. Therefore, to convert 2.2 pounds to kilograms, you multiply 2.2 by 0.4536.

When you calculate:

[

2.2 \text{ lbs} \times 0.4536 \text{ kg/lb} \approx 1.0 \text{ kg}

]

Thus, the equivalent of 2.2 pounds is approximately 1 kilogram. This makes the answer correct, as it accurately reflects the conversion using the standard conversion factor.

In this case, other options represent weights that do not align with the conversion calculation.
