## 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.
