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 · ρA
Symbols
- L = Length
- W = Width
- A = Total area
- m = Total mass
- ρA = 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.
