Unit means part of something. It could mean a unit of measurement, or a unit in an army.

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

Some other ideas come from this word:

• Unity is what is found when parts are joined into one.
• To unite is the act of joining parts together.

For example, a football team may be called "X United". This means that the town of X has come together to support the group.
