Units are very important in our day to day lives. Whether you are buying, bread, butter, milk, floor, working out in a gym, playing football or even refueling in a local gas station, there are units that define that process.
Units, according to Oxford dictionary is a quantity chosen as a standard in terms of which other quantities may be expressed. There are many different activities. While some units are universally accepted others only work within smaller areas. Basically, units can be divided into capacity, weight/mass, length, time and temperature.
