How to Calculate luminance?
luminance calculator uses Luminance=Electric Current/(Area*Cosine) to calculate the Luminance, The luminance formula is defined as the ratio between the current and the product of the area and cosine at a surface. It is denoted as L. Luminance and is denoted by L symbol.
How to calculate luminance using this online calculator? To use this online calculator for luminance, enter Electric Current (i), Area (A) and Cosine (cosθ) and hit the calculate button. Here is how the luminance calculation can be explained with given input values -> 22.91831 = 20/(50*0.01745329251994).
