Unit is representation of any of any physical parameter with its magnitude. Engineers and scientists mainly use much numbers of units. There are several unit systems as like metric, British and so on. Every engineer have to know about the conversion factors of units that used in your daily life.
As like for example, which unit you prefer to express the room size of your house? meter or feet? i mostly prefer feet so i can imagine the size. If some one said me room size is X meter then i just calculate easily multiply it 3.28 tentatively and set the size of room in mind. Its just one type of habit even i mostly use "m" as unit of measurement in other cases.
Here i collected some engineering unit conversion factors, that might be useful for you. take a look at these followings.....
