hectocandela to megacandela
Convert hectocandela (hcd) to megacandela (Mcd). Use an editable luminous intensity converter, conversion formula, and reference table.
1 hcd = 0.0001 Mcd
Conversion formula
One hectocandela equals 0.0001 megacandela. Multiply your value in hectocandela by this factor to get megacandela. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 hectocandela:5 × 0.0001 = 0.0005 Mcd

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 hectocandela is 100 base units; one megacandela is 1,000,000 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
How do I convert hcd to Mcd?
Multiply the quantity in hcd by 0.0001. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the megacandela to hectocandela converter.
