Frequently Asked Questions

What is a meter-candle?
Meter-candle is an older unit of illuminance equal to one lumen per square meter and numerically the same as lux.

Is there any difference between meter-candle and candela steradian per square meter?
No, both units are numerically equivalent; meter-candle is simply an older term for what is now commonly called lux or candela steradian per square meter.

Why convert from meter-candle to candela steradian per square meter?
Conversion helps align older lighting data and literature with modern photometric units used in current lighting design and instrument calibration.

Key Terminology

Meter-candle [m*c]
An older unit of illuminance equal to one lumen per square meter, representing illumination at one meter from a one candela source.
Candela steradian per square meter
A unit measuring illuminance equivalent to lux, defined as luminous flux incident on a surface per unit area.
Lux
The SI unit of illuminance, numerically equal to meter-candle and candela steradian per square meter.
