What does candela per square foot measure?

Candela per square foot is a luminance unit expressing the luminous intensity emitted or reflected by a surface per unit area of one square foot, indicating the apparent brightness.

Why convert candela/square foot to stilb?

Converting candela/square foot to stilb helps translate luminance values between imperial and CGS units, which is useful in comparing historical photometric data with modern measurements.

Is stilb widely used today?

No, stilb is a CGS unit less common in modern use, so interpretation and application require care and contextual understanding.
