Question

How many feet are in $ 1 $ yard?

Answer 1

Hint: Convert the given value in the required specific units by using the conversion equation. Using the formula will find the relation for the given number and simplify the equation using the basic mathematical calculations.

Complete step-by-step answer:
The units are the standards for the measurement of the physical quantities which needs to be clear to be useful. Units are the internationally accepted standards for measurements of the physical quantities.
Different types of system of units are –
SI (International system of units)
The SI units are the standards of measurement defined by the international system of units.
MKS (Meter-kilogram-second) system
The MKS system is the system of units, where length is measured in meters, mass in kilogram and time in seconds.
CGS (centimetre-gram-second) system
The CGS system is the system of units, where length is measured in centimetres, mass in gram and time in seconds.
 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 yard differs a lot.
We know the basic relation between feet and yard.
 $ 1{\text{ yard}} = 3{\text{ feet}} $
This is the required solution.
So, the correct answer is “3 feet”.

Note: 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.
