What does candela per square centimeter measure?

It measures luminance as the luminous intensity emitted per unit projected area of a surface, commonly used for small emitting areas.

Why is 555 nm used in this conversion?

Because 555 nm corresponds to the photopic peak of human visual sensitivity, making it useful for relating radiometric and photometric quantities.

Can this conversion be used for large light sources?

It is primarily intended for small emitting areas where angle and wavelength specificity are important, so use with caution for larger sources.
