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 It represents the illuminance produced by a standard candle at a distance of one meter, providing a historical reference for light measurement that predates the modern SI system.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.

Lumen per Square Meter

lm/m²

Definition

The Lumen per Square Meter is a unit of illuminance that is numerically equivalent to the lux. It represents the luminous flux per unit area, emphasizing the flux aspect of light measurement and providing a direct relationship between light output and surface illumination.

History/Origin

Derived from the fundamental definition of the lux as one lumen per square meter. It provides an alternative way to express illuminance that emphasizes the luminous flux component, making it useful in calculations involving light sources and their output.

Current Use

Widely used in lighting calculations and photometric applications where the relationship between luminous flux and surface area is important. It provides a practical way to understand illuminance in terms of light source output and surface coverage.
