User Guide

This calculator is used to determine the total mass of an item from the measured length and width 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 formulas used by this calculator to determine mass from length, width and area density are:

A = L · W

m = A · ρ_A

m = L · W · ρ_A

Symbols

• L = Length
• W = Width
• A = Total area
• m = Total mass
• ρ_A = Area density

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

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.
