What does lumen per square meter per steradian measure?

It measures luminance, representing luminous intensity per unit area and solid angle, indicating how bright a surface appears in a given direction.

Why convert to lambert from lumen/sq. meter/steradian?

Converting to lambert helps compare modern SI measurements to older CGS-based photometric data and supports traditional brightness specifications in optical and photographic contexts.

Is lambert an SI unit?

No, lambert is a non-SI unit used mainly in CGS systems and specific industries like optical engineering and cinema projection.
