## User Guide

This calculator is used to determine the total area of an item from the total mass measured with a specified area density. Along with the calculated total area, a conversion scale showing a range of mass versus area 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 total area and area density is:

A = m / ρ_{A}

#### Symbols

- A = Total area
- m = Total mass
- ρ
_{A}= Area density

### Total Mass

Enter the total mass of an item and select the applicable mass 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 Area

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