The adult weighs 75 kg. Calculate the adults weight in kilograms (kg) to pounds (lbs). Tip: Use the measurement conversion chart in your textbook. Be sure to show your work and round your final answer to 2 decimal places.
The correct answer and explanation is :
To convert the adult’s weight from kilograms (kg) to pounds (lbs), you will need to use the conversion factor between these two units of mass. The standard conversion factor from kilograms to pounds is:
1 kg = 2.20462 lbs
Conversion Process:
Given:
- The weight of the adult in kilograms = 75 kg
- Conversion factor = 1 kg = 2.20462 lbs
To convert 75 kg to pounds, you multiply the weight in kilograms by the conversion factor:
[
\text{Weight in pounds} = \text{Weight in kilograms} \times \text{Conversion factor}
]
[
\text{Weight in pounds} = 75 \, \text{kg} \times 2.20462 \, \text{lbs/kg}
]
[
\text{Weight in pounds} = 165.3465 \, \text{lbs}
]
Now, rounding the result to two decimal places:
[
\text{Weight in pounds} \approx 165.35 \, \text{lbs}
]
Final Answer:
The adult’s weight in pounds is approximately 165.35 lbs.
Explanation:
The conversion of weight between kilograms and pounds is based on the fact that these units are used in different measurement systems. Kilograms are part of the metric system, which is used widely across the world, while pounds are used primarily in countries like the United States.
In practical scenarios, converting between kilograms and pounds is commonly required for various purposes, such as health and fitness, shipping, or travel. To ensure that the conversion is accurate, it is essential to use the correct conversion factor (1 kg = 2.20462 lbs). This constant factor helps ensure that the two measurements of weight are consistent and comparable. Rounding the result to two decimal places makes the final value easier to understand and apply in everyday contexts, especially when dealing with weight for tasks like medical appointments, luggage limits, or fitness tracking.
Thus, by multiplying the adult’s weight by the conversion factor, we can confidently say that their weight in pounds is 165.35 lbs.
