What does lumen/sq. meter/steradian measure?

It measures luminance, the luminous intensity emitted or reflected per unit area per unit solid angle, indicating surface brightness in a given direction.

Are lumen/sq. meter/steradian and nit the same?

Yes, one lumen/sq. meter/steradian is equal to one nit, but nit is a non-SI unit commonly used in display and lighting industries.

Converting to nits helps specification and comparison of display and lighting brightness in a familiar unit widely accepted across various applications.
