What Is This Tool?
This converter helps translate luminance values from candela per square inch to candela per square meter. It enables consistent brightness evaluation by converting between imperial and SI units commonly used in photometric and display technology fields.
How to Use This Tool?
- Enter the luminance value in candela per square inch (cd/in²) you want to convert
- Select the input unit as candela per square inch and the output as candela per square meter
- Click the convert button to get the equivalent luminance in candela per square meter
- Use the results to compare or specify brightness in SI units
Key Features
- Converts luminance units from cd/in² to cd/m² for precise brightness analysis
- Supports display brightness, instrument panel, and lighting design applications
- Browser-based and user-friendly interface suitable for engineers and designers
- Provides quick examples to demonstrate common conversions
Examples
- 2 candela/square inch equals 3100.0062 candela/square meter
- 0.5 candela/square inch equals 775.00155 candela/square meter
Common Use Cases
- Specifying display luminance for TVs, monitors, smartphones, and HDR screens
- Characterizing brightness of automotive, avionics, and instrument panel backlights
- Evaluating architectural lighting and ensuring proper illumination of surfaces
- Testing and regulating luminance for road signs and safety signage
Tips & Best Practices
- Ensure luminance measurements are taken over planar surfaces for accurate conversion
- Use consistent viewing geometry to interpret luminance values properly
- Verify uniformity of luminous intensity when measuring small luminous indicators
- Consider surface reflectance properties when comparing brightness across materials
Limitations
- Conversion applies only to luminance measured across flat surfaces with accurate area definition
- Variations in viewing angle and surface reflectivity may affect brightness perception
- Unit conversion does not address differences in physical measurement conditions
Frequently Asked Questions
- What is the difference between candela/square inch and candela/square meter?
- Candela per square inch measures luminance over an area in square inches, commonly used in older displays and certain instruments, whereas candela per square meter is the SI standard measuring luminance over square meters, used broadly in modern displays and lighting.
- Why convert candela/square inch to candela/square meter?
- Converting to candela per square meter standardizes brightness measurements, allowing consistent comparison across devices and applications using different area units.
- Is the conversion formula fixed for all luminance measurements?
- Yes, the fixed conversion is 1 candela/square inch equals 1550.0031 candela/square meter, but measurement conditions like surface and viewing geometry affect interpretation.
Key Terminology
- Candela per square inch (cd/in²)
- A unit of luminance measuring luminous intensity distributed over one square inch of surface, used in photometric and certain display engineering contexts.
- Candela per square meter (cd/m²)
- The SI unit of luminance quantifying luminous intensity per square meter of projected area, commonly used in modern display brightness and lighting design.
- Luminance
- A measure of the luminous intensity emitted or reflected from a surface per unit area in a specific direction, indicating how bright the surface appears to an observer.
