femtocandela to nanocandela
Convert femtocandela (fcd) to nanocandela (ncd). Use an editable luminous intensity converter, conversion formula, and reference table.
1 fcd = 0.000001 ncd
Conversion formula
One femtocandela equals 0.000001 nanocandela. Multiply your value in femtocandela by this factor to get nanocandela. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 femtocandela:5 × 0.000001 = 0.000005 ncd

About these measurements
Luminous intensity is visible-light output per unit solid angle in a direction.
The base reference used here is the candela. One femtocandela is 1e-15 base units; one nanocandela is 1e-9 base units.
Important distinctions
Candela is a directional quantity and cannot be converted directly to lumens without geometry.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
