What Is This Tool?
This tool converts luminance values from lambert, a non-SI unit commonly used in CGS systems, to candela per square inch, a unit widely used in display and photometric engineering to measure surface brightness.
How to Use This Tool?
-
Enter the luminance value in lambert [L] you wish to convert
-
Select lambert [L] as the source unit and candela per square inch as the target unit
-
Click convert to obtain the equivalent luminance in candela per square inch
Key Features
-
Simple conversion between lambert [L] and candela/square inch with a fixed conversion rate
-
Browser-based and user-friendly interface for quick luminance calculations
-
Supports conversions relevant to optical, display, avionics, and automotive lighting contexts
Examples
-
3 Lambert [L] equals 6.1608241851 candela/square inch
-
0.5 Lambert [L] converts to 1.02680403085 candela/square inch
Common Use Cases
-
Translating older CGS-based luminance measurements to modern display units
-
Specifying brightness levels for CRT and early flat-panel screens
-
Photometric evaluation of small luminous indicators and instrument-panel backlights
Tips & Best Practices
-
Ensure input luminance values are measured from uniform surfaces for accurate conversion
-
Use the tool for quick unit translations when dealing with historical or legacy photometric data
-
Be mindful of differences in area units when interpreting results in practical applications
Limitations
-
Lambert is a non-SI unit, so precision may vary when converting to candela per square inch
-
Area unit differences between square centimeters and square inches can introduce rounding variations
-
Measurements depend on surface uniformity which affects conversion accuracy
Frequently Asked Questions
-
What is the lambert unit used for?
-
The lambert is a CGS luminance unit used for measuring brightness of self-luminous or diffusely reflecting surfaces, commonly in optical engineering and printing.
-
Why convert lambert to candela per square inch?
-
Converting lambert to candela/square inch helps interpret older CGS photometric data into units suited for modern display and small-area luminance measurements.
-
Does this tool consider measurement precision?
-
The tool provides direct conversion based on a fixed rate but users should consider measurement precision and surface uniformity when using results.
Key Terminology
-
Lambert [L]
-
A non-SI CGS unit of luminance representing brightness of self-luminous or diffusely reflecting surfaces.
-
Candela per square inch
-
A unit measuring luminance as luminous intensity per unit apparent area in inches, used in photometric and display engineering.
-
Luminance
-
The measure of luminous intensity emitted or reflected from a surface in a given direction per unit area.
