Unit

Unit means part of something: a ~ in an army/air force, a navy. Component, building block of constructions and molecules.

It could mean a unit of measurement, ~ of currency (£$¥¤€).

Units sometimes means the digit in a number on the right, which is also called the "ones".

In exact sciences use is made of cgs/psi/cal and m kg s/N/J systems. The SI units in calculation and measurement prevail.

Some other ideas come from this word:

• Unity is what is found when parts are joined into one.

  2. Trinity (3 in 1) in theology.
• To unite is the act of joining parts together.
