Luminance Unit Converter

Luminance refers to the amount of light that is emitted or reflected from a surface in a specific direction per unit of area. It is an important concept in lighting design, photography, and visual arts. The standard unit of measurement for luminance is candela per square meter (cd/m²).

Here are some examples of luminance in real-world scenarios:

Display technology: Luminance is an important parameter for displays such as televisions, computer monitors, and smartphones. The brightness of the display is measured in cd/m², and higher luminance values usually result in better visibility in bright ambient lighting conditions.

Lighting design: Luminance is used in lighting design to ensure that the lighting in a space is appropriate for the task at hand. For example, the luminance of a desk lamp should be higher than that of ambient lighting in a room to provide adequate illumination for reading or working.

Photography: Luminance is a key factor in photography and is used to describe the brightness and contrast of an image. In digital cameras, luminance is measured in terms of the number of photons captured by each pixel.
