What is the mass in kg of a person who weighs 185 pounds?

Answer 1

Step 1:The relationship between kilograms and pounds can be written as $1\text{kg}=2.20\text{lb}$.

Step 2:To get the mass of person in kg. Divide the $2.20\text{lb}$ in $185\text{lb}$.

$m=\frac{185\text{lb}}{2.20\text{lb}}\text{kg}=84.2\text{kg}$

Hence mass of person is $84.2\text{kg}$.
