Identify the given quantity and the conversion factor. Here, you have 30.4 pounds (lb) and the conversion factor 1 lb = 0.454 kg.
Set up the conversion equation to convert pounds to kilograms by multiplying the given pounds by the conversion factor: \(\text{mass in kg} = 30.4 \ \text{lb} \times 0.454 \ \frac{\text{kg}}{\text{lb}}\).
