## User Guide

This calculator is used to determine the area density from the measured mass, length and width of an item. Along with the calculated area density, two conversion scales will show a range of mass with a fixed area, and a range of area with a fixed mass, converted to area density, relating to each calculated result.

### Formula

The formulas used by this calculator to determine mass from area and area density are:

A = L · W

ρ_{A} = m / A

#### Symbols

- L = Length
- W = Width
- A = Total area
- ρ
_{A}= Area density - m = Total mass

### Total Mass

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

### Length

Enter the length of the rectangular item to be calculated, and select the applicable measurement units.

### Width

Enter the width of the rectangular item to be calculated, and select the applicable measurement units.

### Total Area

This is the total area coverage calculated from the length and width above. Select the required area measurement units to display the result.

### Area Density

This is the area density of the item measured, and the value is calculated once you select the required mass and unit area measurement units.
