What Is This Tool?
This converter helps translate luminance measurements labeled in "bril"—a nonstandard or proprietary unit—into lumen per square meter per steradian, which is equivalent to candela per square meter and widely used in photometry and display brightness specifications.
How to Use This Tool?
-
Input the luminance value in bril units
-
Select bril as the initial unit and lumen/sq. meter/steradian as the target unit
-
Click convert to see the equivalent brightness in lumen/sq. meter/steradian
-
Use the converted value for standardized measurements or further analysis
Key Features
-
Converts from the nonstandard unit bril to lumen/sq. meter/steradian
-
Supports luminance measurement translations for scientific and engineering contexts
-
Easy-to-use browser-based interface
-
Enables replacement of proprietary terms with recognized photometric units
-
Suitable for display technology and lighting design applications
Examples
-
10 Bril equals 3.1830988618379e-7 Lumen/sq. meter/steradian
-
100 Bril equals 3.1830988618379e-6 Lumen/sq. meter/steradian
Common Use Cases
-
Replacing nonstandard bril units in legacy or proprietary documents with standardized luminance units
-
Specifying display brightness for devices like monitors, smartphones, and TVs
-
Designing lighting and signage to ensure proper brightness and reduce glare
-
Performing optical and photometric measurements for calibration and evaluation
Tips & Best Practices
-
Confirm the exact meaning of bril from original sources before converting
-
Use converted values for comparison only when bril’s definition is clear
-
Rely on lumen/sq. meter/steradian or cd/m² for scientific or engineering specifications
-
Be cautious with conversions due to the very small conversion rate involved
Limitations
-
"Bril" is not a standardized luminance unit and may vary in meaning
-
Conversion results depend on assumed interpretations of bril’s definition
-
Due to the tiny conversion factor, bril may not represent typical luminance scales
-
Converted values could have uncertainties without confirmed definitions
Frequently Asked Questions
-
Is bril a standard unit for luminance?
-
No, bril is not widely recognized or standardized. It is often a proprietary or local term and should be verified by original sources.
-
Why convert bril to lumen per square meter per steradian?
-
Because bril is nonstandard, converting to lumen/sq. meter/steradian ensures values are standardized and comparable in scientific and engineering contexts.
-
Can I use bril values directly in lighting design?
-
It's recommended to replace bril with standard units like lumen/sq. meter/steradian or candela per square meter for accuracy in design and specifications.
Key Terminology
-
Bril
-
A nonstandard, local, or proprietary luminance unit with no widely recognized definition; usage requires confirmation from the original source.
-
Lumen per square meter per steradian
-
An SI-compatible unit of luminance expressing luminous intensity from a surface area in a given solid angle, equivalent to candela per square meter.
-
Luminance
-
The measure of luminous intensity emitted, reflected, or transmitted from a surface per unit projected area and unit solid angle.
