Common Questions
Is one nit equal to one candela per square meter?
Yes. Nit is the common name for one candela per square meter.
What is the difference between luminance and illuminance?
Luminance describes light emitted or reflected toward the viewer from a surface. Illuminance describes light arriving on a surface and is measured in lux.
Can nits be converted directly to lumens?
Not without more information. Lumens describe total luminous flux, while nits depend on luminous intensity, projected area, and direction.
Why can two displays with the same nit rating look different?
Contrast, black level, reflections, color, viewing conditions, measurement window, and sustained output all affect perceived image brightness.
