The stilb is a unit of luminance in the centimeter-gram-second (CGS) system, symbolized as 'sb'. It represents the brightness of a surface emitting or reflecting light uniformly over an area. Defined as one candela per square centimeter, the stilb measures how much luminous flux is visible in a given direction. Although not commonly used today, it serves as an important historical reference in photometry. Its value is typically used in scientific contexts to understand and quantify light intensity over surfaces. By grasping the concept of stilb, users gain insight into older measurement systems.
Definition of Foot-lambertA foot-lambert, symbolized as 'ft-L', is a unit of luminance in the foot-pound-second (FPS) system. It quantifies the brightness perceived by the human eye from a surface. Defined as one lumen per square foot, it represents the illumination provided by a light source spread evenly over a surface. This unit finds application in industries such as photography, film, and television, where accurate luminance measurements are critical. Although replaced by more modern units like candela per square meter, foot-lambert remains relevant in certain scenarios. Understanding foot-lambert helps in appreciating historical and practical aspects of luminance measurement.
| Stilb (sb) | Foot-lambert (ft-L) |
|---|---|
| 1 sb | 291.9 ft-L |
| 2 sb | 583.8 ft-L |
| 3 sb | 875.7 ft-L |
| 4 sb | 1167.6 ft-L |
| 5 sb | 1459.5 ft-L |
| 6 sb | 1751.4 ft-L |
| 7 sb | 2043.3 ft-L |
| 8 sb | 2335.2 ft-L |
| 9 sb | 2627.1 ft-L |
| 10 sb | 2919 ft-L |
1 sb = 291.9 ft-L
1 ft-L = 0.00343 sb
Example 1:
Convert 5 sb to ft-L:
5 sb = 5 × 291.9 ft-L = 1459.5 ft-L
Example 2:
Convert 3.5 sb to ft-L:
3.5 sb = 3.5 × 291.9 ft-L = 1021.65 ft-L
The Stilb to Foot-lambert Converter traces its roots to the necessity of understanding different luminance units across measurement systems. Historically, the stilb, part of the CGS system, and the foot-lambert, from the FPS system, were used in various scientific fields. This converter emerged to bridge the gap, allowing professionals to seamlessly transition between these units. Over time, as modern units like candela per square meter took precedence, this tool remained crucial for specific applications, ensuring precision and consistency in luminance measurement.
