The cost per single unit of measure (e.g., per ounce, per item). It is calculated by dividing the total price by the quantity.

What units should I use?

Use the same unit type for both products. It can be ounces, grams, liters, count — as long as both use the same unit.

Is bigger always cheaper per unit?

Usually, but not always. Some smaller packages may be on sale and have a better unit price than the bulk option.
