What is the candela per square inch unit used for?

It measures luminance as luminous intensity per square inch, typically used for specifying display brightness in CRTs and certain early flat-panel screens, as well as instrument panel backlights.

Why convert candela per square inch to lambert?

Converting to lambert is useful for comparing older photometric data expressed in CGS units and for applications in optical engineering and photographic contexts where lambert is traditionally used.

Is the lambert unit widely used in modern measurements?

No, lambert is a non-SI unit and is less commonly used today, which may limit its relevance in some contemporary scientific or engineering fields.
