About the Luminous Intensity Converter

Luminous intensity describes the directional strength of a source in candelas, unlike illumination at a surface or luminance from an extended source. LEDs, beacons, headlights, and photometric testing use the distinction. This page retains the standard SI relationship while keeping customary and legacy units explicit, which is important when a specification crosses disciplines.

Enter a value to see the conversion immediately—for example, 2.5 kilocandelas equals 2,500 candelas. For a related check, use the Luminance Converter and Illumination Converter; those tools describe a different but commonly connected quantity.
