What Is This Tool?
This converter allows you to transform luminance values from candela per square centimeter, a unit used primarily for small, intense emitting areas, into lumen per square meter per steradian, the standard SI unit used in photometry and visual ergonomics.
How to Use This Tool?
-
Enter the luminance value expressed in candela per square centimeter.
-
Select the input unit as candela/square centimeter and the output unit as lumen/sq. meter/steradian.
-
Initiate the conversion to get the equivalent luminance value in lumen per square meter per steradian.
Key Features
-
Converts luminance measurements between candela/square centimeter and lumen/sq. meter/steradian.
-
Supports unit conversion relevant to display engineering, lighting design, and photometric measurements.
-
Browser-based tool that is simple and fast to use with no installation required.
Examples
-
2 candela/square centimeter converts to 20000 lumen/sq. meter/steradian.
-
0.5 candela/square centimeter converts to 5000 lumen/sq. meter/steradian.
Common Use Cases
-
Converting brightness values of small high-intensity display elements such as camera viewfinders and LEDs.
-
Comparing luminance levels of CRT phosphors, OLED subpixels, and other display components.
-
Ensuring proper brightness specifications in lighting design, signage, and instrument calibration.
Tips & Best Practices
-
Ensure that the luminance is uniformly distributed over the small emitting surface when converting.
-
Use this conversion to compare luminance across different unit systems in photometric and ergonomic contexts.
-
Be mindful that small changes in candela/square centimeter lead to significant differences in lumen/sq. meter/steradian values.
Limitations
-
Candela/square centimeter measures luminance on very small areas, so uniformity assumptions influence accuracy.
-
The high conversion factor means numerical precision is important to avoid large errors in the converted value.
Frequently Asked Questions
-
What does candela per square centimeter measure?
-
It measures the luminous intensity emitted per unit projected area of a very small surface, commonly used for small, high-intensity emitting areas.
-
How is lumen per square meter per steradian related to candela per square meter?
-
They are equivalent units, both quantifying luminance as luminous intensity per unit area per solid angle.
-
Why is the conversion factor 10,000?
-
Because one candela per square centimeter equals 10,000 candela per square meter, which corresponds to 10,000 lumen per square meter per steradian.
Key Terminology
-
Candela per square centimeter
-
A unit of luminance expressing luminous intensity per unit area, used for small, intense light-emitting surfaces.
-
Lumen per square meter per steradian
-
The SI unit of luminance equivalent to candela per square meter, measuring luminous intensity per area per solid angle.
-
Luminance
-
The measure of luminous intensity emitted or reflected from a surface per unit area per unit solid angle.
