Enter the basic paper area (in^2) and the weight per unit area of the paper (lb/in^2) into the Basis Weight Calculator. The calculator will evaluate the Basis Weight.

## Basis Weight Formula

The following two example problems outline the steps and information needed to calculate the Basis Weight.

BSW = BA * WPA

Variables:

• BSW is the Basis Weight (lb)
• BA is the basic paper area (in^2)
• WPA is the weight per unit area of the paper (lb/in^2)

## How to Calculate Basis Weight?

The following steps outline how to calculate the Basis Weight.

1. First, determine the basic paper area (in^2).
2. Next, determine the weight per unit area of the paper (lb/in^2).
3. Next, gather the formula from above = BSW = BA * WPA.
4. Finally, calculate the Basis Weight.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

basic paper area (in^2) = 30

weight per unit area of the paper (lb/in^2) = .020

BSW = BA * WPA = ?
