Reference

How luminous intensity conversion works

Luminous intensity measures visible-light power per unit solid angle with human visual weighting. Values are normalized to Candela before conversion to the requested output unit.

Values are converted to candela first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Accuracy note: SI relationships follow the cited reference. Conventional and domain-specific factors use the established ConvertWin factor inventory; verify safety-critical work against the governing standard.
