What does candela per square meter measure?

It quantifies the luminous intensity a surface emits or reflects per unit projected area, showing how bright it appears under specific viewing conditions.

When should I use candela per square inch?

This unit is typically used for brightness measurements in older or specialized display devices and for photometric testing where area is expressed in inches.

Why convert between these two luminance units?

The conversion bridges metric and imperial luminance measures, helping compare displays or lighting systems that use different unit standards.
