What Is This Tool?
This unit converter facilitates the conversion of illuminance measurements from lux (lx) to lumen per square meter (lm/m^2). Both units measure the luminous flux incident on a surface per unit area based on human photopic vision, making them effectively equivalent.
How to Use This Tool?
- Input the illuminance value in lux (lx) you wish to convert.
- Select lux as the starting unit and lumen per square meter as the target unit.
- Click the convert button to obtain the equivalent value in lm/m^2.
- Review the result which reflects the direct equivalence between these units.
Key Features
- Converts illuminance values between lux and lumen per square meter instantly.
- Browser-based tool requiring no installation.
- Supports user inputs for diverse lighting measurement needs.
- Clear presentation of equivalent units based on SI derived units.
Examples
- 300 lux equals 300 lumen per square meter.
- 1000 lux is equivalent to 1000 lumen per square meter.
Common Use Cases
- Designing lighting standards for indoor spaces such as offices and classrooms.
- Measuring outdoor illumination like daylight and sunlight intensity.
- Calibrating and testing lamps, displays, and lux meters.
- Setting proper lighting exposure in photography and cinematography.
- Controlling light delivery for plant growth in horticulture.
Tips & Best Practices
- Ensure measuring devices are properly calibrated to improve accuracy.
- Consider uniformity of light distribution when interpreting results.
- Use the converter to compare and specify light levels effectively across applications.
- Recognize that lux and lumen per square meter represent the same illuminance quantity.
Limitations

- Accuracy depends on uniform light distribution and the calibration of illumination meters.
- Environmental factors affecting measurement may influence the reliability of results.
Frequently Asked Questions
- Are lux and lumen per square meter different units?
- No, lux and lumen per square meter are identical units of illuminance representing one lumen of luminous flux per square meter of surface.
- Why convert lux to lumen per square meter if they are equal?
- The conversion helps express illuminance in equivalent terms useful for various applications like lighting design, measurement, and quality testing.
- What affects the accuracy of illuminance measurements?
- Measurement accuracy depends on factors like calibration of instruments and uniformity of light distribution on the surface.
Key Terminology
- Lux [lx]
- The SI derived unit of illuminance, equal to one lumen per square meter, measuring luminous flux incident on a surface weighted by human photopic vision.
- Lumen per square meter [lm/m^2]
- A unit quantifying illuminance as one lumen of luminous flux uniformly incident on one square meter of surface, equivalent to lux.
- Illuminance
- The amount of visible light received per unit area on a surface, measured by units such as lux or lumen per square meter.
