How to convert nits to candelas per square meter
Luminance describes directional brightness weighted for human vision. It differs from illuminance on a surface and cannot be converted to lux without geometry.
Use x for the value in nit, b for the intermediate value in cd/m², and y for the result in cd/m².
cd/m² = nit
Worked examples
10 nit ≈ 10 cd/m²
Step 1: (10 × 1) ≈ 10 cd/m².
Step 2: 10 ÷ 1 ≈ 10 cd/m².20 nit ≈ 20 cd/m²
Step 1: (20 × 1) ≈ 20 cd/m².
Step 2: 20 ÷ 1 ≈ 20 cd/m².
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Nits
Nits (nit) measures luminance under the conventions above. The base value in cd/m² is (x × 1), where x is the numerical value in nit. Factors shown here are rounded for display; calculations use the stored factor.
About Candelas per square meter
Candelas per square meter (cd/m²) measures luminance under the conventions above. The base value in cd/m² is (x × 1), where x is the numerical value in cd/m². Factors shown here are rounded for display; calculations use the stored factor.
