Convert 22 kilograms to pounds. (round your answer to the nearest tenth)
1 lb = 0.4536 kg
1 kg = 2.205 lbs
22 kgs is equivalent to lbs
The Correct Answer and Explanation is:
To convert 22 kilograms to pounds, we use the conversion factor (1 \text{ kg} = 2.205 \text{ lbs}).
Step-by-step Calculation:
- Start with the given weight in kilograms:
(22 \text{ kg}). - Multiply the kilogram value by the conversion factor:
(22 \text{ kg} \times 2.205 \text{ lbs/kg} = 48.51 \text{ lbs}). - Since the question asks for the answer to be rounded to the nearest tenth, we round 48.51 to 48.5 pounds.
So, 22 kilograms is approximately 48.5 pounds.
Detailed Explanation:
The process of converting kilograms to pounds involves using a known conversion factor, which tells us how many pounds are equivalent to one kilogram. In this case, 1 kilogram equals 2.205 pounds. This conversion factor comes from the relationship between the metric system (kilograms) and the imperial system (pounds).
When performing such conversions, it is important to ensure that the units cancel out correctly. For example, in this calculation, kilograms cancel out, leaving only pounds. The exact multiplication gives 48.51 pounds, but rounding to the nearest tenth is a common practice for simplification, especially in healthcare settings where quick and practical approximations are often needed.
This type of conversion is essential in fields such as nursing and healthcare, where patient weights are often measured in kilograms, but medication dosages, nutritional requirements, or equipment settings may need to be interpreted or communicated in pounds. Being able to perform such conversions accurately ensures that medical professionals can make appropriate decisions for patient care, like determining drug dosages based on weight or calculating proper body mass index (BMI) values.
