What does candela per square inch measure?

It measures luminance as the luminous intensity emitted or reflected from a surface per square inch area, indicating how bright a surface appears in a particular direction.

When should I use candela per square foot instead of candela per square inch?

Use candela per square foot when working with larger surface brightness assessments or in areas where imperial units based on square feet are standard, such as cinema screen calibration or lighting design.

How is the conversion between candela per square inch and candela per square foot performed?

The conversion multiplies the candela per square inch value by 144.0000000001 to get the equivalent candela per square foot luminance.
