unit of luminous intensity, 1950, from Latin candela (see candle).

(Abbreviated cd.) A unit of luminous intensity expressed in lumen per steradian (lm sr-1). The candela was first defined as 1/60 the luminous intensity, in the perpendicular direction, of a 1 cm2 blac [..]

A unit used to measure light intensity.

The luminous intensity in a specified direction, of a monochromatic source which has a frequency of 540 x 1012 Hz and which has a radiant intensity, in the specified direction, of (1/683) watt per steradian.

A unit of luminous intensity in a given direction, equal to one lumen per steradian.

Abbreviated cd, the International System of Units standard unit of measurement of luminous intensity. The candela is equal to the luminous intensity in a given direction of a source that emits monochr [..]

taper, candle

A unit of light intensity, a standard candle. (Lighting)

A unit of luminosity used to express the intensity of a light source as measured in a specific direction. The higher the number of candela measured, the greater the intensity of the light.

The luminous intensity, in a given direction, of a source that emits monochromatic radiation with wavelengths weighted to the standardized model of sensitivity of the human eye.

(n) the basic unit of luminous intensity adopted under the Systeme International d'Unites; equal to 1/60 of the luminous intensity per square centimeter of a black body radiating at the temperatu [..]

The SI unit of luminous intensity. The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 1012 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian.

 - The standard unit for luminous intensity. One candela is equal to one lumen per steradian.

In reference to lighting, this is an obsolete unit of luminous intensity. Also called "candle" or "standard candle."

N F tallow candle/taper; waxen cord; fire (L+S); small taper/candle (Ecc)

A unit used to measure luminous intensity in the International System of Units. One candela is the amount of light intensity generated by one ordinary candle.

an SI (International System of Units) unit of luminous intensity. One candela is one lumen per steradian, where a steradian is a unit of measure relating the angle subtended at the center of a sphere [..]

A unit of light measurement that refers to the luminous intensity from a light source in a specific direction.

Unit of luminous intensity. One candela is one lumen per steradian. Formerly called the candle.

(can dell' ah) a measurement of directional light intensity from a point source.

Unit of light intensity; fundamental dimension of lighting engineering. 1 cd is defined as the light intensity emitted by a monochromatic light source with a radiant power of 1/683 W at 555 nm.

Unit of luminous intensity. One candela is one lumen per steradian. Formerly called the candle.

A measure of luminous intensity, or power emitted by a light source in a particular direction. A common candle emits light with a luminous intensity of roughly one candela.

A candela is a measurement of luminous intensity and is a replacement to the candle.

the base unit to measure luminous intensity, i.e., the power emitted by a light source in a particular direction. Read more.

Unit of luminous intensity. 1 candela is equal to 1 lumen per solid angle.

unit which expresses the luminous intensity of a light source.

Candela (cd) is a standard unit of measurement defined in the International System of Units (SI) for luminous intensity. Technically since 1979, the candela has been defined by the General Conference [..]

The luminous intensity emitted by a light source. One candela emits one lumen per steradian.

The Systeme International d'Unities (SI) of luminous intensity. One candela is one lumen per steradian. Formerly, candle.

Short form of Candelaria.
