What Is This Tool?
This online converter enables the transformation of illumination measurements from lumen per square meter (lm/m^2), the SI unit of illuminance, to the centimeter-candle (cm*c), an outdated candle-based unit. It assists users in interpreting or comparing historical lighting data and legacy photometric values.
How to Use This Tool?
- Enter the illuminance value in lumen per square meter (lm/m^2)
- Choose lumen per square meter as the source unit
- Select centimeter-candle as the target unit
- Click the convert button to obtain the equivalent value in cm*c
- Use the results to analyze or compare lighting data from older sources
Key Features
- Converts illuminance values between lumen/square meter and centimeter-candle units
- Supports conversion of lighting data useful for historical and legacy measurements
- Simple and browser-based tool requiring no installation
- Provides examples to illustrate conversion results
- Facilitates understanding of obsolete photometric units
Examples
- 1000 lumen/square meter equals 0.1 centimeter-candle
- 500 lumen/square meter converts to 0.05 centimeter-candle
Common Use Cases
- Verifying and interpreting vintage lighting levels from photographic or cinematic materials
- Converting legacy optical instrument readings that use candle-based illuminance units
- Analyzing historical photometry data that predate lux unit standards
- Supporting academic research involving older illumination datasets
Tips & Best Practices
- Remember that centimeter-candle is an obsolete unit replaced by lux
- Use this conversion mainly for historical or legacy data interpretation
- Be aware that real-world measurements may differ from the ideal conversion assumptions
- Cross-check converted values when applying to modern lighting design contexts
- Consider staying consistent with SI units for contemporary applications
Limitations
- Centimeter-candle is no longer a standard unit and is obsolete
- Conversion assumes one candela point source which may not reflect real conditions
- Values converted are very small which reduces practical usage in modern tasks
- Modern illumination engineering prefers lux over candle-based units
Frequently Asked Questions
- What does lumen per square meter measure?
- Lumen per square meter measures illuminance, representing luminous flux per unit area and is equivalent to lux.
- Why convert lumen/square meter to centimeter-candle?
- This conversion helps interpret or compare older lighting specifications and legacy photometric data expressed in candle-based units.
- Is centimeter-candle still used in modern measurements?
- No, the centimeter-candle is an obsolete unit replaced by lux in current applications.
Key Terminology
- Lumen per square meter (lm/m^2)
- An SI derived unit for illuminance, quantifying luminous flux per area, equivalent to lux.
- Centimeter-candle (cm*c)
- An outdated unit of illuminance based on the light from one candle at one centimetre distance, replaced by lux.
- Illuminance
- A measurement of the amount of visible light falling on a given surface area.
