Step 1:I'll solve this unit conversion problem step by step:
Step 2:: Recall the conversion factor between pounds and kilograms
1 \text{ kg} = 2.20462 \text{ pounds}
Step 3:: Set up the conversion calculation
\frac{159 \text{ pounds}}{2.20462 \text{ pounds/kg}}
To convert pounds to kilograms, we'll divide the number of pounds by the conversion factor:
Step 4:: Perform the calculation
159 \div 2.20462 = 72.1 \text{ kg}
Step 5:: Round to a reasonable number of significant figures
Since the original measurement (159 pounds) has three significant figures, we'll round our answer to three significant figures.
Final Answer
Key points: - Used the standard conversion factor of 1 kg = 2.20462 pounds - Divided pounds by pounds/kg to get kilograms - Rounded to three significant figures for consistency with input measurement
