Lux to Nits Calculator

Formula

The formula to convert Lux to Nits is:

\[ N = \frac{L}{A} \]

Where:

\( N \) is the luminance in nits (cd/m²)
\( L \) is the illuminance in lux (lx)
\( A \) is the area over which the illuminance is measured (square meters)

What are Lux and Nits?

Lux (lx) is a unit of illuminance, which measures the amount of light that falls on a surface. Nits (cd/m²) are a unit of luminance, which measures the brightness of a light source as perceived by the human eye. The conversion from lux to nits is useful in various fields such as photography, cinematography, and display technology, where understanding the brightness of a light source is crucial.

Example Problem

Let's assume the following values:

Illuminance (L) = 500 lux
Area (A) = 2 m²

Using the formula:

\[ N = \frac{500}{2} = 250 \, \text{cd/m²} \]

The Luminance is 250 cd/m².
