Light converters offer conversions of luminous intensity, luminance, illumination, and digital image resolution units.
The luminous intensity converter offers conversion between various luminous intensity units. The luminous intensity can be defined as the quantity of visible light that is emitted in unit time per unit solid angle. The SI base unit of luminous intensity is candela \(\left[\mathrm{cd}\right]\).
The luminance converter offers conversion between various luminance units. The luminance can be defined as a photometric measure of the luminous intensity per area of light traveling in a given direction. The luminous intensity can be described as the amount of light that passes through, is emmited from, or is reflected from a particular area, and falls within a given solid angle. The luminance in SI is measured in \(\left[\frac{\mathrm{cd}}{\mathrm{m}^2}\right]\).
The illumination converter offers conversion between various illumination units such as centimeter-candle, foot-candle, flame, phot, nox, candela steradian/square meter, lumen/square meter, lumen/square centimeter, lumen/square foot, and watt/square centimeter.
The digital image converter offers conversion between various digital image units such as dot/meter, dot/millimeter, dot/inch, and pixel/inch.
