What does candela per square meter measure?

Candela per square meter quantifies the luminous intensity emitted or reflected from a surface per unit area, describing how bright that surface appears to an observer.

Why convert to lumen per square centimetre per steradian?

This unit helps measure luminance at smaller scales and solid angles, which is useful for high-brightness sources and detailed optical measurements.

Does this converter work for all luminance levels?

While generally useful, extremely high or low luminance values require careful calibration, and surface non-uniformity may limit accuracy with simple conversion.
