Square Footage Calculator is published by Mycelgrid LLC as a focused browser-based area calculator.
Calculation scope
The app supports rectangles, squares, triangles, circles, and known areas. It normalizes measurement units to one internal area basis, totals the unrounded row areas, and converts the result to square feet, square yards, square meters, and acres.
Browser-local processing
Area names, measurements, and calculations stay in the current browser page for the session. The calculator does not require an account, database, or remote calculation service.
Measurement limits
This app is not a land survey, GIS tool, appraisal, certified residential gross-living-area measurement, roofing calculator, material takeoff, or project-cost estimator. Verify measurements and use the standard required for any regulated or contractual purpose.

Privacy, data and limits
Square Footage Calculator processes area names, dimensions, units, quantities, and calculated results only in this browser page. It does not upload calculator work, maintain an app-owned measurement history, account, cloud copy, or recovery service. Share App shares only the canonical app URL, not entered measurements, labels, or results.
Results are simple-shape geometry and unit conversions based on the values you enter. The app does not perform a land survey, trace parcel or map boundaries, certify residential gross living area, account for roof pitch, calculate material quantities or waste, price work, or replace a measurement standard required for a regulated, contractual, appraisal, or construction purpose.
