Express 160 pounds (Ibs ) in kilograms (kg). Round your final answer
The correct answer and explanation is:
To convert pounds to kilograms, we use the conversion factor that 1 pound is equal to approximately 0.453592 kilograms. The formula to convert pounds to kilograms is: Weight in kg=Weight in lbs×0.453592\text{Weight in kg} = \text{Weight in lbs} \times 0.453592
For 160 pounds, the calculation would be: 160×0.453592=72.57472 kg160 \times 0.453592 = 72.57472 \, \text{kg}
When rounded to the nearest whole number, the weight is approximately 73 kg.
Explanation:
Pounds and kilograms are both units used to measure weight or mass, but they belong to different measurement systems. Pounds are part of the Imperial system commonly used in the United States, while kilograms are part of the Metric system, which is more commonly used in the rest of the world. Since the two units measure the same quantity (mass), a conversion is necessary when switching between them.
The key conversion factor, 1 pound = 0.453592 kilograms, allows us to transform the value from pounds to kilograms. This factor is derived from the relationship between the two measurement systems. Using the formula, multiplying the number of pounds by 0.453592 gives the mass in kilograms. In practical terms, understanding how to convert units like this is essential for international travel, scientific work, and many other fields where measurements may be needed in different units.
In this case, the final result of 160 pounds is approximately 73 kilograms when rounded. When rounding, one typically looks at the decimal place to the right of the tenths and rounds up or down based on that value. In this case, since the hundredths digit is 7 (which is more than 5), we round up to 73.
