Mobile luminous intensity and luminous flux converter

Maximum luminous intensity: Iv = cd
Cone full angle: 2θ = °
Equivalent solid angle: Ω = ster
Total luminous flux: F = lm

Enter all the known data in the calculator below and leave the fields to calculate blank, than click the "calculate" button to compute and fill in the blanks.

This calculator converts between luminous flux and luminous intensity using only the cone full angle. This is a rough approximation, see the full page for details.
