The formula to calculate Candela (\(cd\)) from Lux (\(lx\)) is:
\[ cd = lx \times d^2 \]
Where:
Lux (lx) is a measure of illuminance, the total amount of visible light illuminating a point on a surface. Candela (cd) measures the luminous intensity in a specific direction.
The distance is the space between the light source and the point where the illuminance is measured, in meters.
Let's assume the following values:
Using the formula:
\[ cd = 500 \times 2^2 \]
Evaluating:
\[ cd = 500 \times 4 = 2000 \]
The Candela is 2000 cd.
