What Is This Tool?
This tool converts illumination measurements from foot-candle, a unit commonly used in North American lighting for everyday environments, into nox, a specialized unit for very low light levels such as night-time or near-dark conditions.
How to Use This Tool?
- Enter the illumination value in foot-candle (ft*c or fc)
- Select foot-candle as the source unit and nox as the target unit
- Click the convert button to get the equivalent value in nox
- Use the result to analyze lighting conditions from common to very low levels
Key Features
- Converts foot-candle (ft*c, fc) to nox efficiently
- Supports lighting design, astronomy, environmental, and optical testing applications
- Provides clear unit definitions and use cases
- Suitable for translating typical indoor lighting to extremely low illumination values
- Browser-based and easy to use without installation
Examples
- 2 Foot-candle equals 21527.8208334 Nox
- 0.5 Foot-candle converts to 5381.95520835 Nox
Common Use Cases
- Specifying lighting levels for offices, retail areas, and building regulations
- Measuring exposure in photography, film, and stage lighting setups
- Setting recommended illumination in museums, galleries, and greenhouses
- Describing night-time illumination like moonlight and starlight in astronomy
- Planning dark-sky environments and low stray lighting in exterior lighting designs
- Testing sensitive optical sensors under very low light conditions
Tips & Best Practices
- Ensure correct unit selection to accurately represent illumination levels
- Consider the large numeric difference between foot-candle and nox when interpreting results
- Use this conversion to bridge common lighting measures with specialized low-light requirements
- Apply contextual knowledge to avoid misinterpretation especially when working with very low light units
- Use precise measurement tools compatible with the units involved for reliable results
Limitations
- Foot-candle measures much higher illuminance than nox, leading to very large conversion values
- The vast difference in unit scale may complicate practical interpretation without context
- Measurement precision and the relevance of extremely low illumination units should be considered
- This tool does not provide additional physical or scientific details beyond conversion rates
Frequently Asked Questions
- What is a foot-candle?
- A foot-candle is a non-SI unit of illuminance equal to one lumen per square foot, often used in North American lighting to measure luminous flux on a surface.
- What does the nox unit measure?
- Nox is a specialized unit used to describe very low light levels equal to 1 millilux, commonly applied in night-time or near-dark illumination measurements.
- Why convert from foot-candle to nox?
- Converting from foot-candle to nox helps translate typical indoor lighting levels into very low illumination values needed for applications involving night-time, environmental studies, and sensitive optical testing.
Key Terminology
- Foot-candle [ft*c, fc]
- A non-SI unit of illuminance defined as one lumen per square foot, commonly used in North American lighting practices.
- Nox
- A historical/specialized unit of illuminance equivalent to one millilux, used to quantify very low light levels like moonlight or starlight.
- Illuminance
- The measure of luminous flux incident on a surface per unit area, indicating how much light falls on that surface.
