Candelas to hectocandelas converter

Convert candelas (cd) to hectocandelas (hcd). Calculate any value, follow the unit-factor steps and check a conversion table.

Updated · How we check
TRY YOUR OWN NUMBER Reverse conversion

Use a decimal point, such as 2.5. Enter a value in cd; the result is in hcd.

Hectocandelas≈ 0.01hcd

Formula

hcd ≈ cd × 0.01

Worked example

Convert 1 cd to hcd:

1 cd ≈ 0.01 hcd

Multiply your cd value by the factor above. The calculator uses the full conversion factor before rounding the displayed answer.

What candelas measure

Candelas (cd) represent luminous intensity. One unit equals 10^0 cd. The candela is the SI base unit of luminous intensity in a specified direction.

Reading the result in hectocandelas

Hectocandelas (hcd) represent luminous intensity. One unit equals 10^2 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 1e0 cd; the output unit has a factor of 1e2 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.
