What Is This Tool?
This unit converter helps you transform illuminance measurements from lux, a common photometric unit, into candela steradian per square meter, another equivalent unit measuring luminous flux per unit area. The tool supports accurate and consistent conversions used in lighting design, calibration, and measurement.
How to Use This Tool?
- Enter the illuminance value in lux (lx) in the input field.
- Select the 'lux [lx]' as the source unit and 'candela steradian/sq. meter' as the target unit.
- Click the convert button to get the equivalent value in candela steradian per square meter.
- Review the results for use in lighting design or calibration tasks.
Key Features
- Converts between lux (lx) and candela steradian/sq. meter (cd·sr·m⁻²).
- Reflects the numerical equivalence of these units for illuminance.
- Supports applications in architectural and outdoor lighting design.
- Facilitates calibration and testing of lighting equipment and meters.
- Browser-based and easy to use with instant results.
Examples
- 300 lx is equal to 300 candela steradian/sq. meter.
- 1000 lx converts directly to 1000 candela steradian/sq. meter.
Common Use Cases
- Designing and verifying indoor lighting levels in offices, classrooms, and workplaces.
- Assessing outdoor and street lighting illuminance for safety and compliance.
- Calibrating and testing lamps, displays, and light meters in photometric contexts.
- Measuring daylight conditions ranging from overcast skies to direct sunlight.
- Ensuring consistency in lighting measurements across different units and instruments.
Tips & Best Practices
- Ensure you select the correct units before performing conversions for accuracy.
- Use this conversion under photopic vision conditions suitable for daytime lighting.
- Be aware of industry-specific standards that may influence unit preference.
- Regularly calibrate your instruments to ensure reliable measurement outputs.
- Interpret results carefully when dealing with different spectral sensitivity scenarios.
Limitations
- Though lux and candela steradian/sq. meter are numerically equivalent, unit choice depends on industry conventions.
- Conversion assumes photopic conditions and may not apply to measurements involving other visual responses.
- Instruments calibrated differently might require distinct interpretation despite equivalent values.
Frequently Asked Questions
- What does lux measure?
- Lux measures illuminance, which is the luminous flux incident on a surface per unit area, weighted by the human photopic visual response.
- Is 1 lux equal to 1 candela steradian per square meter?
- Yes, 1 lux is numerically equivalent to 1 candela steradian per square meter in photometric contexts.
- When should I use candela steradian per square meter instead of lux?
- Use candela steradian per square meter when working with photometric and lighting-engineering applications that require this unit, especially in calibration and detailed lighting design.
Key Terminology
- Lux [lx]
- An SI derived unit of illuminance representing luminous flux per square meter, adjusted for the human photopic visual response.
- Candela steradian/sq. meter (cd·sr·m⁻²)
- A photometric unit equivalent to lux that measures illuminance as luminous flux per unit area.
- Illuminance
- The amount of luminous flux incident on a surface per unit area.
