Question

How do you convert $ 9 $ feet to meters?

Answer 1

Hint: Convert the given value in the required specific units by using the conversion equation. Use the formula - $ 1{\text{ feet}} = 0.305{\text{ metres}} $ . Place the relation for the given number and simplify the equation using the basic mathematical calculations.

Complete step-by-step answer:
We know that the basic relation between feet and metres.
 $ 1{\text{ feet}} = 0.305{\text{ metres}} $
Place the value in the given value –
 $ {\text{9 feet}} = 9 \times 0.305{\text{ metres}} $
Simplify the above equation finding the product of the terms in the above expression –
 $ {\text{9 feet}} = 2.745{\text{ metres}} $
This is the required solution.
So, the correct answer is “2.745 meters”.

Note: It is very important to know the difference between the system of units and the conversional ratios between them. Since if we say mass of one it does not make any sense, also length of one feet and one meter differs a lot.
 Also, remember the conversional relations of the different physical quantities and apply accordingly. This conversion is most important in dealing with the physical quantities expressed with different systems of units.
