What Is This Tool?
This unit converter allows you to transform illumination values measured in the historical unit centimeter-candle into the informal unit flame. It helps interpret old photometric data into more qualitative and descriptive lighting terms suitable for informal or field settings.
How to Use This Tool?
-
Enter the illumination value in centimeter-candle units
-
Select the target unit as flame
-
Click the convert button to get the equivalent flame value
-
Use the result for qualitative or descriptive lighting assessments
Key Features
-
Converts between the obsolete centimeter-candle and informal flame units of illumination
-
Supports historical and qualitative lighting interpretations
-
Includes examples to illustrate typical conversions
-
Browser-based and easy to use for quick conversions
-
Useful in fields like conservation, firefighting, archaeology, and research
Examples
-
2 centimeter-candle [cm*c] equals approximately 464.5152 flame
-
0.5 centimeter-candle [cm*c] converts to about 116.1288 flame
Common Use Cases
-
Interpreting legacy photometric data measured in centimeter-candle
-
Translating precise historical illumination figures into informal light descriptions
-
Qualitative lighting assessments in archaeological or anthropological research
-
Estimating light conditions in safety, firefighting, and outdoor fieldwork
-
Understanding older optical instrument lighting specifications
Tips & Best Practices
-
Use this converter when precise lux measurements are unavailable or unnecessary
-
Apply results mainly for qualitative or informal lighting descriptions
-
Refer to historical context when working with centimeter-candle values
-
Be aware of the approximate nature of conversion to flame due to lack of standardization
Limitations
-
Flame is not a formal or standardized unit, limiting measurement precision
-
Centimeter-candle is obsolete and replaced by lux in modern applications
-
Conversion outcomes are approximate and may not match actual perceived brightness
Frequently Asked Questions
-
What is a centimeter-candle?
-
A centimeter-candle is an outdated unit of illuminance that represented the light on a surface one centimetre from a point source of one candle, historically used in photometry.
-
Why convert from centimeter-candle to flame?
-
Conversion to flame helps translate precise historical lighting data into informal, qualitative terms useful in fieldwork or non-technical contexts.
-
Is flame a standard measurement unit?
-
No, flame is an informal light descriptor without standardization, often used as a rough reference for light from open flames.
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.
-
Flame
-
An informal, non-standard light descriptor referring to illumination from an open combustion source, mainly used for qualitative assessments.
-
Illuminance
-
The amount of light falling on a surface, measured in various units including lux, centimeter-candle, and informally as flame.
