# Unit vs. Each: What's the Difference?

By Janet White || Updated on October 4, 2023
"Unit" refers to a single complete thing often used as a standard of measurement, while "Each" signifies every one of two or more considered individually or one by one.

## Key Differences

"Unit" and "Each" are terms often used interchangeably, but they have distinct meanings and usages. "Unit" is a term used to denote a single entity, often one that's part of a larger group. It can represent a standard of measurement or a component of a larger system. "Each," however, is a term that's used to refer to every individual item in a set or group.
When talking about quantity or measurement, "Unit" emphasizes the singular nature of the item or the standardization aspect. For instance, a box may contain multiple units of a product. "Each," on the other hand, refers to all the items within a group on an individual basis. For instance, each product in the box might have a unique serial number.
In sales or retail, the distinction becomes clearer. A price might be set per unit, indicating the cost of one item. Meanwhile, "each" is used to specify that the given price or condition applies to every single item separately.
To put it simply, while both "Unit" and "Each" can often refer to individual items, "Unit" emphasizes the idea of standardized, singular entities often within a larger system, and "Each" highlights the individual nature of items within a group.
