What Is This Tool?
This converter helps you translate illumination measurements from nox, a unit used for very low light levels typically encountered in night-time or near-dark conditions, into the centimeter-candle [cm*c] unit, an obsolete measure formerly used in photometry for very high illuminance close to point light sources.
How to Use This Tool?
- Enter the value in nox representing the low-level illumination you want to convert
- Select the target unit as centimeter-candle [cm*c]
- Click convert to see the equivalent value expressed in the historical illumination unit
- Use the converted results to compare with legacy lighting specifications or research data
Key Features
- Converts illumination from nox to centimeter-candle [cm*c] accurately based on established conversion rates
- Supports understanding specialized low-light conditions in legacy and modern contexts
- Browser-based, easy-to-use interface for quick unit conversion
- Helpful for comparing modern low illuminance measurements to historical photometric data
Examples
- 10 nox converts to 1 × 10^-6 centimeter-candle [cm*c]
- 100 nox converts to 1 × 10^-5 centimeter-candle [cm*c]
Common Use Cases
- Describing natural night illumination levels such as moonlight or starlight in astronomy
- Planning and designing exterior lighting with considerations for dark-sky preservation
- Comparing low-level illumination data with older photometric units in historical research
- Calibrating sensitive optical sensors and imaging systems under low illumination conditions
Tips & Best Practices
- Apply this conversion when needing to interpret low illuminance data within historical contexts
- Keep in mind the large difference in scale between nox and centimeter-candle units
- Use this tool to aid in understanding archival lighting specifications expressed in candle-based units
- Verify the context of your illumination data to ensure appropriate usage of these units
Limitations
- Conversion results yield extremely small values due to the vast difference in unit scales
- Centimeter-candle is an outdated unit largely replaced by the modern lux unit
- Precision is limited because of the historical definitions and approximations of these units
- Direct practical comparisons between nox and centimeter-candle can be constrained by their scale disparity
Frequently Asked Questions
- What is a nox?
- A nox is a specialized, historical unit of illuminance used to represent very low light levels, equal to 1 millilux (0.001 lux), commonly used for describing night-time or near-dark conditions.
- Why convert from nox to centimeter-candle?
- Conversions help relate very low-level illumination measurements to older photometric units, facilitating comparison with historical lighting data and specifications.
- Is the centimeter-candle still used today?
- No, the centimeter-candle is an obsolete unit that has been mostly replaced by the SI unit lux in modern photometry.
Key Terminology
- Nox
- A historical unit of illuminance equal to 1 millilux, used to quantify very low light levels like moonlight or starlight.
- Centimeter-candle [cm*c]
- An obsolete unit of illuminance representing the illumination at one centimetre from a point source of one candle, formerly used in photometry and replaced by lux.
- Illuminance
- A measurement of the luminous flux incident on a surface per unit area, indicating how much light is received.
