What is a Nit in luminance measurement?

A Nit is a unit of luminance defined as one candela per square meter, commonly used to describe the brightness of screens and displays.

Why convert Nit to Apostilb?

Conversion to Apostilb is useful for referencing older photometric standards and ensuring compatibility with historical luminance data.

Is Apostilb still widely used?

No, Apostilb is largely obsolete and non-SI; it mostly appears in historical or legacy photometric contexts.
