What is the main difference between square foot (US survey) and the international square foot?

The square foot (US survey) is defined based on the U.S. survey foot, resulting in a slightly different area than the international square foot, which uses a foot based on 0.3048 meters.

Why is the sabin used in acoustic calculations?

The sabin quantifies the absorption from a unit area of perfectly absorbing surface, helping to sum total sound absorption in a space for room acoustic designs.

Can I convert other area units to sabins with this tool?

This specific tool focuses on converting from square foot (US survey) to sabin as described, without including other area units.

Click the convert button to get the equivalent value in sabins.

Key Features

Converts area units from square foot (US survey) to sabin with an exact conversion rate.
Supports use cases in acoustical engineering and legal land measurements.
Browser-based tool providing quick conversion for acoustic and surveying needs.

Examples

10 square foot (US survey) converts to 10.00004 sabins.
100 square foot (US survey) converts to 100.0004 sabins.

Common Use Cases

Recording parcel and deed areas in U.S. cadastral and legal surveys using survey-foot standards.
Calculating surface absorptions to determine room reverberation times in acoustic design.
Comparing absorption performance of materials and panels in soundproofing projects.

Tips & Best Practices

Ensure you select the correct units to maintain accuracy, especially when working with historical surveys.
Use the sabin measurement in contexts where acoustic absorption characteristics are relevant.
Consider material absorption properties in addition to area to accurately assess sound absorption.

Limitations

The US survey foot differs slightly from the international foot, affecting precise acoustic calculations.
Sabins measure acoustic absorption, so surface properties influence their effective use beyond raw area conversions.

Key Terminology

Square Foot (US Survey): A unit of area based on the square of the U.S. survey foot, used mainly in U.S. land surveys and legal property descriptions.
Sabin: A unit measuring acoustic absorption from one unit area of a perfectly absorbing surface, used in room acoustic calculations.
Conversion Rate: The factor used to convert one unit to another; here, 1 square foot (US survey) equals 1.000004 sabin.
