Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Identify the given information
- Weight = $$120 \text{ lb}
- We need to convert this to mass in kilograms
Step 3:: Recall the conversion factors
- $$1 \text{ lb} = 0.453592 \text{ kg}
- Conversion from pounds (lb) to kilograms (kg)
Step 4:: Perform the conversion calculation
- Mass in kg = Weight in lb $$\times$$ Conversion factor
- 120 \text{ lb} \times 0.453592 \frac{\text{kg}}{\text{lb}} = 54.4310 \text{ kg}
Step 5:: Round to an appropriate number of significant figures
- $$54.4 \text{ kg}
- Typically, round to 2 - 3 significant figures
Final Answer
Note: The conversion uses the standard conversion factor between pounds and kilograms, converting the weight directly to mass. This assumes standard Earth gravity conditions.
