PLSS Double Proportion Calculator
Introduction & Importance
The PLSS Double Proportion Calculator is an essential tool for land surveyors and GIS professionals. It helps calculate the area of a square based on the side length of a rectangle, using the PLSS (Public Land Survey System) double proportion formula.
How to Use This Calculator
- Enter the side length of the rectangle in the ‘Value’ field.
- Enter the proportion of the rectangle’s side length to the square’s side length in the ‘Proportion’ field.
- Click ‘Calculate’.
Formula & Methodology
The PLSS double proportion formula is: Area = Value * (Proportion / (1 – Proportion))
Real-World Examples
Example 1
Side length of rectangle = 1000 ft, Proportion = 0.5
| Value | Proportion | Area |
|---|---|---|
| 1000 | 0.5 | 1250000 sq ft |
Example 2
Side length of rectangle = 1500 ft, Proportion = 0.6
| Value | Proportion | Area |
|---|---|---|
| 1500 | 0.6 | 2550000 sq ft |
Data & Statistics
| Proportion | Area (1000 ft side length) | Area (1500 ft side length) |
|---|---|---|
| 0.5 | 1250000 sq ft | 1875000 sq ft |
| 0.6 | 1500000 sq ft | 2550000 sq ft |
