What Is This Tool?
This converter transforms measurements from lumen per square centimeter—a unit measuring light intensity on a small surface area—into meter-candle [m*c], an older unit representing illuminance over a larger area and equivalent to lux.
How to Use This Tool?
-
Enter the value in lumen per square centimeter you wish to convert
-
Select lumen/square centimeter as the source unit
-
Choose meter-candle [m*c] as the target unit
-
Submit the input to receive the equivalent value in meter-candle
Key Features
-
Converts between lumen/square centimeter and meter-candle [m*c] accurately
-
Browser-based, easy-to-use interface for illumination unit conversions
-
Supports applications in LED manufacturing, microscopy, and lighting design
Examples
-
0.5 lumen/cm² converts to 5000 meter-candle
-
2 lumen/cm² converts to 20000 meter-candle
Common Use Cases
-
Measuring brightness output of small high-power LEDs or LED dies
-
Illuminance measurement on microscope slides or small sensor surfaces
-
Calibrating or comparing brightness of small optical components and displays
-
Specifying or comparing room and work surface lighting levels
-
Interpreting historical lighting data using meter-candle terminology
-
Calibrating illuminance in photography, display testing, and lighting design
Tips & Best Practices
-
Ensure units are correctly selected before conversion to avoid errors
-
Use this conversion when comparing micro-scale measurements to conventional lighting specifications
-
Be aware of the context to avoid confusion between meter-candle and lux despite their equivalence
-
Consider spatial distribution before applying conversions across large areas
Limitations
-
Lumen/square centimeter is meant for very small, localized measurements and scaling to meter-candle can oversimplify spatial variations
-
Historical references to meter-candle might cause confusion with lux even though they represent the same illuminance
-
Accurate conversion assumes uniform luminous flux distribution which may not always apply
Frequently Asked Questions
-
What does lumen per square centimeter measure?
-
It is a photometric measure of illuminance that quantifies the luminous flux falling on one square centimeter of a surface, reflecting perceived brightness weighted by the human eye’s response.
-
Is meter-candle the same as lux?
-
Yes, the meter-candle is an older unit of illuminance that is numerically equal to the SI unit lux.
-
Why convert from lumen/cm² to meter-candle?
-
Conversion helps translate precise small-scale measurements into more commonly used illuminance units for broader lighting comparisons and design purposes.
Key Terminology
-
Lumen/square centimeter
-
A measurement of illuminance representing luminous flux per square centimeter, used to quantify brightness on very small surfaces.
-
Meter-candle [m*c]
-
An older unit of illuminance equal to one lumen per square meter, historically used in lighting design and equivalent to lux.
-
Illuminance
-
The total luminous flux incident on a surface per unit area, measuring how much light illuminates that surface.
