What Is This Tool?
This unit converter transforms illuminance measurements from candela steradian per square meter, equivalent to lux, into centimeter-candle, an obsolete photometric unit. It assists in interpreting and comparing modern lighting data with older candle-based units.
How to Use This Tool?
- Enter the illuminance value in candela steradian per square meter
- Select the unit candela steradian/sq. meter as the input unit
- Choose centimeter-candle [cm*c] as the output unit
- Click convert to obtain the equivalent illuminance in cm*c
Key Features
- Converts illuminance from candela steradian per square meter to centimeter-candle
- Offers an accessible way to compare modern and historical photometric data
- Browser-based tool requiring no installation or special software
- Supports use cases in lighting design, research, and historical data restoration
Examples
- Convert 10 cd·sr·m⁻² to cm*c: result is 0.001 cm*c
- Convert 500 cd·sr·m⁻² to cm*c: result is 0.05 cm*c
Common Use Cases
- Comparing current illuminance measurements with historical lighting data
- Analyzing early photographic lighting conditions using legacy units
- Restoring and calibrating optical instruments recorded in candle-based units
- Studying the evolution of lighting engineering standards over time
Tips & Best Practices
- Understand that centimeter-candle is an obsolete measurement mainly for legacy data
- Use this converter when examining historical or older photometric records
- Consider the context and calibration differences when comparing units
- Confirm the definition of the candle unit used in historical sources for accurate conversion
Limitations
- Centimeter-candle is outdated and rarely applied in contemporary lighting contexts
- Direct comparisons between cm*c and modern units require nuanced understanding
- Conversion assumes the candle equals one candela, which may vary historically
Frequently Asked Questions
- What does candela steradian per square meter measure?
- It measures illuminance, the luminous flux per unit area, and is equivalent to the lux.
- Why is centimeter-candle considered obsolete?
- Because it was replaced by the SI unit lux and is mainly found in historical photometric data.
- When should I use this conversion?
- Use it to interpret or compare modern illuminance values with older data expressed in candle-based units.
Key Terminology
- Candela steradian per square meter (cd·sr·m⁻²)
- A unit of illuminance equal to one lumen per square meter, numerically the same as lux.
- Centimeter-candle (cm*c)
- An obsolete illuminance unit corresponding to illumination one centimetre from a one-candle point source, previously used in photometry.
- Illuminance
- The measure of luminous flux arriving at a surface per unit area.
