What Is This Tool?
This converter transforms luminance measurements from candela per square centimeter, a unit for small high-intensity surfaces, into candela per square meter, the SI standard unit for luminance used in broader applications like display brightness and lighting design.
How to Use This Tool?
-
Enter the luminance value in candela per square centimeter.
-
Choose the input unit as candela/square centimeter and the output unit as candela/square meter.
-
Click convert to obtain the equivalent luminance in candela per square meter.
-
Use the result for display engineering, lighting design, or safety signage assessment.
Key Features
-
Converts luminance values between candela/square centimeter and candela/square meter instantly.
-
Supports measurements for small intense light-emitting surfaces and standard SI luminance units.
-
Browser-based and easy to use without the need for specialized software.
-
Helps specify and compare brightness levels across different lighting and display contexts.
Examples
-
2 candela/square centimeters is equal to 20000 candela/square meters (2 × 10000).
-
0.5 candela/square centimeters converts to 5000 candela/square meters (0.5 × 10000).
Common Use Cases
-
Determining brightness of small display components like camera viewfinders and LED indicators.
-
Evaluating luminance of CRT phosphors and OLED subpixels in display panels.
-
Measuring brightness of surgical, inspection lamps, and instrument panels with compact emitting areas.
-
Specifying and regulating display brightness for TVs, smartphones, and HDR screens.
-
Lighting design for architectural interiors and assessment of safety signage luminance.
Tips & Best Practices
-
Ensure uniform luminance distribution assumptions are valid when converting values.
-
Use this conversion primarily for small emitting areas where candela/square centimeter is applicable.
-
Verify measurement precision to capture differences at small scales accurately.
-
Apply the conversion result for consistent standards in display technology and lighting evaluation.
Limitations
-
Candela per square centimeter is less suited for large-area luminance examinations.
-
The conversion presumes consistent luminance across the measured surface and may not fit non-uniform cases.
-
Measurement instruments require sufficient sensitivity to detect precise luminance in small areas.
Frequently Asked Questions
-
What is candela per square centimeter used for?
-
It is commonly used for indicating brightness of very small, intense light-emitting areas such as camera viewfinders, LED indicators, and small display elements.
-
Why convert candela/square centimeter to candela/square meter?
-
Converting to candela/square meter, the SI unit of luminance, allows for standardization and easier comparison across various lighting and display applications.
-
Are there any limitations to this conversion?
-
Yes, such as the assumption of uniform luminance and the requirement for precise measurements, especially since candela/square centimeter applies to small emitting areas.
Key Terminology
-
Candela per square centimeter
-
A luminance unit expressing luminous intensity per small projected area, used for small, intense light sources.
-
Candela per square meter
-
The SI unit of luminance, indicating luminous intensity per unit area, often called nit.
-
Luminance
-
A measure of the luminous intensity emitted or reflected by a surface per unit area in a particular direction.
