What does lumen per square centimetre per steradian measure?

It measures luminance as luminous flux leaving a surface per unit area per unit solid angle, equivalent to candela per square centimetre.

Why use millilambert instead of SI units?

Millilambert remains useful in cinematography and imaging to specify screen luminance and to convert legacy measurements.

Is this conversion useful for general lighting applications?

This conversion is most relevant for small-area, high-brightness measurements rather than broad photometric contexts.
