What are Candela and Watt

Candela is a fundamental unit of luminous intensity in the International System of Units (SI). It quantifies the intensity of light emitted in a specific direction by a source that emits monochromatic radiation of frequency 540 terahertz. The candela is equivalent to one lumen per steradian, representing the light's power per unit solid angle. Historically, it was based on the light emitted by a standard candle, thus its name. Used widely in fields like photography, astronomy, and lighting design, candela helps calibrate devices and ensures consistent light measurements across different industries.

Watt is the SI unit of power, named after James Watt, the inventor of the steam engine. It quantifies the rate of energy transfer or conversion. One watt is equivalent to one joule per second, representing the amount of energy consumed or generated in that time frame. Commonly used to express the power output of engines, electric devices, and light bulbs, watt measures the energy required to perform work or produce heat. Understanding wattage is essential for calculating the efficiency of electrical appliances and systems, making it a critical component in energy management and conservation.

History of Candela and Watt

The Candela/square Foot to Watt/sq. Cm/steradian (at 555 Nm) Converter emerged from the need to quantify light intensity accurately. Initially, the candela unit was derived from a standard candle's luminous intensity. As technology advanced, precise measurement tools became essential, especially in sectors like lighting design and astronomy. The converter aids in translating traditional candela measurements into the more universally applicable watts per square centimeter per steradian, helping professionals and enthusiasts alike understand and apply light intensity in modern contexts.
