What does lumen per square centimeter per steradian measure?

It quantifies the luminous flux passing through a surface area per unit solid angle, equivalent to candela per square centimeter, used to characterize small-area brightness.

Why convert lumen/sq. cm/steradian to stilb?

Converting to stilb allows interpreting and comparing modern photometric measurements with older CGS unit data frequently found in historical and optical research.

Are lumen/sq. cm/steradian and stilb equivalent units?

Yes, 1 lumen/sq. cm/steradian equals exactly 1 stilb, representing the same luminance quantity in SI-derived and CGS systems respectively.

Can I use this tool for calibrating luminance meters?

Yes, it supports calibrating and testing meters by facilitating conversions between small-area high-intensity units and CGS luminance standards.
