How to convert kilocandelas to candelas
A candela equals one lumen per steradian. Total lumens require a known angular distribution; watts require spectral luminous efficacy. Obsolete candle standards are deliberately excluded.
Use x for the value in kcd, b for the intermediate value in cd, and y for the result in cd.
cd = kcd × 1000
Worked examples
10 kcd ≈ 10000 cd
Step 1: (10 × 1000) ≈ 10000 cd.
Step 2: 10000 ÷ 1 ≈ 10000 cd.20 kcd ≈ 20000 cd
Step 1: (20 × 1000) ≈ 20000 cd.
Step 2: 20000 ÷ 1 ≈ 20000 cd.
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 Kilocandelas
Kilocandelas (kcd) measures luminous intensity under the conventions above. The base value in cd is (x × 1000), where x is the numerical value in kcd. Factors shown here are rounded for display; calculations use the stored factor.
About Candelas
Candelas (cd) measures luminous intensity under the conventions above. The base value in cd is (x × 1), where x is the numerical value in cd. Factors shown here are rounded for display; calculations use the stored factor.
