Are lumen/sq. meter/steradian and candela/square meter the same?

Yes, these units are equivalent. One lumen per square meter per steradian equals one candela per square meter, both representing luminance.

What is luminance used for in lighting design?

Luminance helps evaluate how bright surfaces and interiors appear, essential for proper lighting and signage design.

Can this converter be used for display brightness assessment?

Absolutely. Display brightness for screens such as monitors and smartphones is commonly specified in candela per square meter.
