What Is This Tool?
This unit converter allows users to transform illumination measurements from the obsolete centimeter-candle unit to lumen per square centimeter. It provides a practical way to interpret legacy photometric data in modern terms.
How to Use This Tool?
-
Enter the illumination value measured in centimeter-candle (cm*c).
-
Select centimeter-candle as the input unit and lumen/square centimeter as the output unit.
-
Click convert to obtain the equivalent illuminance in lumen per square centimeter.
-
Use the result to analyze or calibrate lighting data according to current standards.
Key Features
-
Converts illumination values from centimeter-candle to lumen/square centimeter accurately.
-
Supports interpretation of historical photometry data and calibration of optical instruments.
-
Browser-based and easy-to-use interface requiring minimal input.
-
Helps in comparing brightness levels of small light sources and optical components.
-
Facilitates updates from obsolete units to modern photometric standards.
Examples
-
5 centimeter-candle [cm*c] converts to 5 lumen/square centimeter.
-
0.1 centimeter-candle [cm*c] converts to 0.1 lumen/square centimeter.
Common Use Cases
-
Updating or interpreting older lighting data expressed in candle-based units.
-
Comparing or calibrating brightness levels for LEDs and filament lamps in historical documents.
-
Measuring illuminance on small sensor surfaces or microscope slides in laboratory settings.
-
Calibrating brightness of small displays and optical components with per-square-centimeter metrics.
Tips & Best Practices
-
Always verify the original context when working with obsolete units like the centimeter-candle to avoid confusion.
-
Use this conversion to align legacy data with modern SI-based measurement units.
-
Be mindful of the very high illuminance values involved due to small measurement areas.
-
Cross-check converted results when calibrating sensitive optical instruments for accuracy.
Limitations
-
Centimeter-candle is an outdated unit and may lead to misunderstandings if not properly contextualized.
-
Both units indicate very high illuminance on small areas, requiring careful scale interpretation.
-
Conversion is direct but users must ensure correct application in modern photometry contexts.
Frequently Asked Questions
-
What is a centimeter-candle?
-
A centimeter-candle is an obsolete unit of illuminance representing the light on a surface one centimetre from a point source of one candle, historically used in photometry.
-
How does lumen/square centimeter relate to lux?
-
One lumen per square centimeter is equivalent to 10,000 lux, quantifying brightness per unit area considering human eye response.
-
Why convert centimeter-candle to lumen/square centimeter?
-
Conversion helps update and interpret legacy photometric data using modern, standardized illumination units.
Key Terminology
-
Centimeter-candle [cm*c]
-
An obsolete illuminance unit representing light on a surface one centimetre from a point source of one candle, historically used in photometry.
-
Lumen/square centimeter
-
A measure of illuminance indicating luminous flux per square centimeter surface area, directly convertible to lux.
-
Illuminance
-
The amount of luminous flux incident on a surface per unit area, perceived as brightness.
