Light bulb are measured in Candela (Cd) for its luminous intensity and Watt for its power consumed.

Foot Candela is the measuring unit for illuminance while candela/meter squared is a measuring unit for luminance,which makes conversion not possible. conversion can be done for units of the same quantity, for example, illuminance units : ft candela = 10.764 lux. To know the difference between luminance & illuminance, you can take a look at http://www.tpub.com/content/gsacriteria/gsa_courtroom_lighting/gsa_courtroom_lighting0012.htm
Physical quantities are quantities that can be measured. For example: water, distance, etc.
it is time
Intensity is measured in Candela. Candela is its SI unit.
Light bulb are measured in Candela (Cd) for its luminous intensity and Watt for its power consumed.
The electricity used by a Lightbuldb is measured in "Watts", the output of the Light (i.e. the Light) is measured in "Candela".
a physical quantity can be measured, like mass; a nonphysical quantity cannot be measured, like feelings or happiness
The unit for intensity of light is candela(cd). However, bulbs are rated by their power usage which is measured in watts(W)
Current is a basic quantity, measured in amperes.
It depends on the quantity being measured. mass: kilogram (kg) distance: meter (m) time: second (s) temperature: kelvin (K) amount of substance: mole (mol) electric current: ampere (A) luminosity: candela (cd)
candela measures the amount of light emitted in the range of a (three- dimensional) angular span.

Air pressure is measured in bar.
In an economy, the quantity of money is measured by the Money Supply. This is the amount of money available in an economy in a specific period of time.
