Tips & Best Practices
-
Always verify the unit consistency when performing conversions
-
Remember that lumen/sq. cm/steradian values are numerically smaller due to unit scaling
-
Use the correct conversion formula to avoid significant errors
-
Consider uniformity assumptions in luminance measurements for accurate results
-
Check calibration standards when working with high-intensity or micro-scale luminance
Limitations
-
Numerical values in lumen/sq. cm/steradian are smaller due to the area unit difference, requiring careful scaling
-
The conversion presumes uniform luminance over the measured area, which may not apply for microscopic variations
-
Measurement errors can occur if unit consistency is not maintained throughout the process
Frequently Asked Questions
