This tool converts luminance (surface brightness) between common photometric units used in lighting design and display engineering.
Enter a value in any unit (for example cd/m², also known as nits) and the converter will calculate the equivalents in units such as foot-lambert (fL) and lambert (L).
Tip: Use consistent decimal formatting (e.g., 12.5) and check significant digits for reporting.
Basic unit dimensions : [length]-2[luminous intensity]
SI Unit : cd/m2
