Watt to Calorie per Second Converter

A watt (W) is the SI unit of power, defined as one joule per second. Named after Scottish inventor James Watt, it represents the rate of energy transfer and is fundamental to all power measurements in the International System of Units.

The watt was named after James Watt in 1882 and became the SI unit of power in 1960. It replaced various earlier power units and provided a unified measure based on the fundamental relationship between energy and time, becoming universal in scientific and technical applications.

Watts are universally used for all power measurements, from small electronic devices to large machinery. They're fundamental in electrical engineering, physics, energy efficiency ratings, and form the basis for all other power unit measurements.

Calorie per second (cal/s) is a unit of power representing the rate of energy transfer of one calorie per second. It's used in thermodynamic applications and provides a direct relationship between thermal energy and power.

Calorie per second developed with early thermodynamic studies and calorimetry. It provided a way to express power in terms of thermal energy units, particularly useful in heat transfer calculations and thermal system analysis.

Calorie per second is used in thermodynamics, heat transfer calculations, and thermal system design. It's found in calorimetry, thermal analysis, and applications where thermal energy rates are more intuitive than electrical power units.
