In the field of engineering, various units are used like meter, kilogram, second.
Example: If we have to measure the distance of the road. We can measure it in meters and further can convert it into different units like a millimeter, centimeter, foot, inch, yard, etc.
Before starting the discussion about measurement units and unit conversion of these measurement units, we will learn about dimensions.

One Dimension:
The dimension which has only single power of the unit is known as a one-dimensional unit. The simplest example of a one-dimensional unit is distance. It is calculated in meters, Kilometres, miles, etc. It can be represented as m^1.
Two Dimension:
The dimension which has two power of the unit is known as a one-dimensional unit. The simplest example of a two-dimensional unit is area. It is calculated in Sq. Yd, Sq.M, Sq.cm, etc., can be represented as m^2.
Three Dimensions:
The dimension which has three power of the unit is known as a three-dimensional unit. The simplest example of a two-dimensional unit is the Tropicana Juice tetra pack. It can be represented as m^3.
Types of Units
- Engineering Units (M.K.S units):- Metres, Centimetres, millimetres
- Architectural units (F.P.S Units):- Foot, Inches, yards
Unit conversion is very important in every engineering field. Every engineer should how to convert one unit to another.
