What Is a Candela per Square Foot?
A candela per square foot is a unit of luminance equal to 10.7639104 candelas per sq. meter (cd/m²), the base unit for luminance. Equal to 10.7639 cd/m². [1]
The candela per square foot is classified as a US customary unit of luminance. Candelas per Square Foot can be abbreviated as cd/ft²; for example, 1 candela per square foot can be written as 1 cd/ft².
When working with candelas per square foot (cd/ft²) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, candelas per square foot (cd/ft²) are widely used across standard luminance applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Stilb?
A stilb is a unit of luminance equal to 10,000 candelas per sq. meter (cd/m²), the base unit for luminance. CGS luminance unit equal to 10,000 cd/m². [2]
The stilb is classified as a metric and SI-compatible unit of luminance. Stilbs can be abbreviated as sb; for example, 1 stilb can be written as 1 sb.
When working with stilbs (sb) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, stilbs (sb) are widely used across large-scale industrial, bulk, and macro-level luminance specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting luminance between candelas per square foot (cd/ft²) and stilbs (sb), keep full floating-point precision (1 cd/ft² = 0.0010764 sb; 1 sb = 929.0304014 cd/ft²) during intermediate calculations and round only the final stilb figure to match your instrument tolerance.
