Conversion assumes uniform measurement conditions; variations can affect equivalence
Frequently Asked Questions
-
What does candela per square inch measure?
-
It measures the luminous intensity emitted or reflected from a surface per square inch in a specified direction, used mainly for photometric and display brightness evaluations.
-
Why convert candela per square inch to stilb?
-
Conversion allows for comparison and interpretation of luminance data across different unit systems, especially when dealing with legacy or historical photometric records.
-
Are stilb units commonly used today?
-
Stilb is a CGS unit less frequently used in modern practice, where SI units like candela per square meter are more common.
Key Terminology
-
Candela per square inch
-
A luminance unit quantifying luminous intensity per square inch of surface, used in photometry and display engineering.
-
Stilb [sb]
-
A CGS unit of luminance equal to 10,000 candela per square meter, used for photometric data in older literature and optical research.
-
Luminance
-
The measure of luminous intensity emitted or reflected from a surface in a specified direction per unit area.
