Frequently Asked Questions
- What is candela steradian per square meter used for?
- It measures illuminance as luminous flux per area, commonly used in lighting design for indoor and outdoor environments and instrument calibration.
- How does foot-candle relate to the lux unit?
- One foot-candle is approximately 10.7639 lux, making it a customary unit for illuminance in North America.
- Why convert between candela steradian/sq. meter and foot-candle?
- Conversion allows adaption between the SI and North American lighting measurement systems for consistent design, compliance, and photographic exposure.
Key Terminology
- Candela steradian per square meter (cd·sr·m⁻²)
- A unit measuring illuminance equal to one lumen per square meter, equivalent to the lux.
- Foot-candle (ft*c, fc)
- A non-SI illuminance unit equal to one lumen per square foot, used primarily in North American lighting practices.
- Illuminance
- The amount of luminous flux incident on a surface per unit area.
