Tips & Best Practices
-
Ensure accurate measurement of luminous surface area when using these units
-
Be cautious integrating with SI-based systems since stilb and candela/cm² are non-SI
-
Use this conversion tool specifically for surface luminance values, not ambient or volumetric light
-
Cross-check converted values when dealing with critical brightness calibration tasks
-
Utilize this tool when working with historical data reported in CGS units for consistent interpretation
Limitations
-
The stilb is a CGS unit and candela per square centimeter is a non-SI derived unit, requiring careful consistency checks
-
These units measure only surface luminance, not volumetric or ambient light intensity
-
Measurement uncertainties in luminous surface area can affect conversion accuracy
-
Not suitable for applications needing SI standard units without appropriate conversion
-
Use caution when mixing with values in candela per square meter or other SI luminance units
Frequently Asked Questions
-
What is stilb [sb] used for?
-
Stilb [sb] is a CGS unit of luminance used to quantify luminous intensity per unit area in optical research and historical photometric data.
-
Why convert stilb to candela per square centimeter?
-
Converting stilb to candela per square centimeter helps translate legacy CGS measurements into a unit better suited for small high-intensity light surfaces common in display technologies.
