Step 1:I'll solve this unit conversion problem step by step:
Step 2:: Recall the conversion factor between pounds (lbs) and kilograms (kg)
The standard conversion is: 1 lb = 0.453592 kg
Step 3:: Set up the conversion calculation
180 \text{ lbs} \times \frac{0.453592 \text{ kg}}{1 \text{ lb}}
Step 4:: Multiply to convert
180 \times 0.453592 = 81.64656 \text{ kg}
Step 5:: Round to a reasonable number of significant figures
Since the original measurement (180 lbs) has 3 significant figures, we'll round our answer to 3 significant figures.
Final Answer
Key Points: - Used precise conversion factor of 0.453592 kg per lb - Multiplied weight by conversion factor - Rounded to match significant figures of original measurement
