What does candela per square centimeter measure?

Candela per square centimeter quantifies luminance as luminous intensity emitted per unit projected surface area, primarily used for small, intense light-emitting areas.

Why is blondel considered an obsolete unit?

Blondel was an early 20th-century unit for luminance, later replaced by the SI unit candela per square meter, leading to its limited use today.

When would I need to convert between candela/square centimeter and blondel?

Conversion is useful when comparing modern luminance data with historical photometry or analyzing older lighting engineering documents referencing blondel units.
