Meter-Candle

m*c

Definition

The Meter-Candle is a unit of illuminance that is numerically equivalent to the lux. It represents the illuminance produced by a standard candle at a distance of one meter, providing a historical reference for light measurement that predates the modern SI system.

History/Origin

Developed as part of early photometric systems where illumination was measured in terms of candle power at specific distances. The meter-candle was used before the adoption of the lux as the standard SI unit, providing a practical way to relate illumination to familiar light sources.

Current Use

Primarily of historical interest, though may still be encountered in older technical specifications or educational contexts. It provides a direct relationship between illumination and the traditional candle standard, helping to understand the evolution of light measurement.

Candela Steradian per Square Meter

cd·sr/m²

Definition

The Candela Steradian per Square Meter is a unit of illuminance that is dimensionally equivalent to the lux. It represents the luminous intensity per unit solid angle per unit area, providing an alternative way to express illuminance in terms of fundamental photometric quantities.

History/Origin

Derived from the fundamental definitions of luminous intensity and solid angle in the SI system. It provides a direct relationship between illuminance and the basic photometric quantities, emphasizing the geometric aspects of light measurement.

Current Use

Used in theoretical photometry and in calculations where the relationship between luminous intensity, solid angle, and area is emphasized. It provides a fundamental understanding of illuminance in terms of basic photometric principles.
