Luminance Converter
Comprehensive Luminance Converter
Luminance is a measure of the brightness of a surface, defined as the luminous intensity per unit area. Our Luminance Converter allows you to easily convert between various units—from the SI standard (candela per square meter) to commonly used units like candela per square centimeter, candela per square foot, and even kilocandela per square meter, stilb, and others. This tool is essential for lighting designers, engineers, and researchers in the fields of optics and display technology.
What Units Are Covered?
Our converter supports a full range of luminance units with conversion factors defined relative to candela per square meter [cd/m²]:
Candela/square meter [cd/m²] (base unit)
Candela/square centimeter: 1 unit = 10,000 cd/m²
Candela/square foot: 1 unit = 10.76391 cd/m²
Candela/square inch: 1 unit = 1550.0031 cd/m²
Kilocandela/square meter: 1 unit = 1000 cd/m²
Stilb [sb]: 1 unit = 10,000 cd/m²
Lumen/sq. meter/steradian: 1 unit = 1 cd/m²
Lumen/sq. cm/steradian: 1 unit = 10,000 cd/m²
Lumen/square foot/steradian: 1 unit = 10.76391 cd/m²
Watt/sq. cm/steradian (at 555 nm): 1 unit = 6,830,000 cd/m²
Nit [nt]: 1 unit = 1 cd/m²
Millinit [mnt]: 1 unit = 0.001 cd/m²
Lambert [L]: 1 unit = 3183.0988618379 cd/m²
Millilambert [mL]: 1 unit = 3.1830988618 cd/m²
Foot-lambert [fL]: 1 unit = 3.4262590996 cd/m²
Apostilb: 1 unit = 0.3183098862 cd/m²
Blondel: 1 unit = 0.3183098862 cd/m²
Bril: 1 unit = 3.1830988618379E-8 cd/m²
Skot: 1 unit = 0.0003183099 cd/m²
How Does It Work?
Our converter uses a two-step process:
Convert to the Base Unit:
The input value is converted to candela per square meter using the conversion factor of the selected “From” unit.Convert to the Target Unit:
The value in cd/m² is then converted to your desired “To” unit using its corresponding conversion factor.
This ensures precise and consistent luminance conversions for all your applications.
