User Guide

This calculator is used to determine the total mass of an item from the total area measured with a specified area density. Along with the calculated total mass, a conversion scale showing a range of areas versus mass with a fixed area density, will also be drawn to relate to each calculated result.

Formula

The formula used by this calculator to determine mass from area and area density is:

m = A * ρ_A

Symbols

• m= Total mass
• A = Total area
• ρ_A = Area density

Total Area

Enter the total area of an item and select the applicable area measurement units.

Area Density

Enter the amount of mass per unit area of the item which has been measured, and select the appropriate units for mass and unit area.

Total Mass

This is the total mass of the item measured, and the value is calculated once you have selected the required mass measurement unit.
