What are units?

Unit is a set of system, which is also measurement units, therefore we are able to measure different things and objects, then compare them when needed.

Why is there different units?

Because of the histories and custom we have in different places and regions, some units have changed and evolved and few remained the same as the originals, so there are some systems with various units and conversions.

But some unit have different meanings and/or represent different numbers/quantities in different systems.

And when you convert one unit to another, always remember that the exact answer you get can contain a slight margin of error, but the error range won’t be big if you leave more decimal places as possible. With that being said, don’t sweat on it.
