What centicandelas measure
Centicandelas (ccd) represent luminous intensity. One unit equals 10^-2 cd. The candela is the SI base unit of luminous intensity in a specified direction.
Reading the result in megacandelas
Megacandelas (Mcd) represent luminous intensity. One unit equals 10^6 cd. The candela is the SI base unit of luminous intensity in a specified direction.
Where this conversion helps
Normalize directional light intensity specifications before comparing their stated values. Candelas, lumens and lux describe different quantities. Beam geometry or area is needed to relate them.
How the scale changes
The input unit has a factor of 1e-2 cd; the output unit has a factor of 1e6 cd. Multiply the entered number by the input factor, then divide by the output factor. The physical quantity stays the same while its numerical representation changes.
Reading very small or large results
Scientific notation keeps very small and large values readable: 2.5e-6 means 0.0000025. The converter calculates with 50 significant digits internally and displays up to 10. Exact unit definitions do not remove uncertainty from the original measurement.
