number
Formula: pounds/2.2 = kg
The Correct Answer and Explanation is :
To convert 130 pounds (lbs) to kilograms (kg), we can use the conversion formula that states (1 \, \text{kg} = 2.2 \, \text{lbs}). Therefore, to find the weight in kilograms, we divide the weight in pounds by 2.2:
[
\text{kg} = \frac{\text{pounds}}{2.2} = \frac{130}{2.2} \approx 59.09
]
When we round this to the nearest whole number, we get 59 kg.
Explanation of the Conversion Process
The conversion from pounds to kilograms is essential in many contexts, especially in health and fitness, where measurements can often be required in different units. The pound is a unit of weight commonly used in the United States and a few other countries, while the kilogram is part of the metric system and is widely used across the world, including in scientific and medical settings.
The conversion factor (2.2) is based on the definition that (1 \, \text{kg}) is approximately equal to (2.2 \, \text{lbs}). This relationship helps us understand how these units relate to one another. By using this factor, we can easily switch between pounds and kilograms, which is particularly useful for those who might be following dietary plans or exercise regimens that specify weight in kilograms.
In this example, knowing that 130 lbs corresponds to about 59 kg helps in contexts such as medical assessments, where healthcare professionals may prefer or require measurements in metric units. Additionally, understanding how to perform these conversions empowers individuals to track their fitness goals more effectively and communicate their progress in a format that may be more universally understood.
In conclusion, converting 130 pounds to kilograms yields a result of approximately 59 kg, which exemplifies the straightforward process of unit conversion based on established relationships between different measurement systems.
