teracandela to decacandela
Convert teracandela (Tcd) to decacandela (dacd). Use an editable luminous intensity converter, conversion formula, and reference table.
1 Tcd = 100,000,000,000 dacd
Conversion formula
One teracandela equals 100,000,000,000 decacandela. Multiply your value in teracandela by this factor to get decacandela. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 teracandela:5 × 100,000,000,000 = 500,000,000,000 dacd

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 teracandela is 1e+12 base units; one decacandela is 10 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
