Formula
Watt = Calories/hour × 1.1630e-3
Worked Example
Example: 5 Calories/hour = 5 × 1.1630e-3 = 5.8150e-3 Watt
To convert Calories/hour to Watt, multiply the Calories/hour value by 1.1630e-3. This factor is derived from the ratio between the two units.
Calories per hour is a unit of power expressing the rate of energy expenditure or transfer in calories per hour. One calorie is the energy needed to raise one gram of water by one degree Celsius.
History
The calorie was first defined by Nicolas Clément in 1824. While largely replaced by the joule in scientific contexts, calories per hour is still occasionally used in nutrition and exercise science to express metabolic rates.
The watt is the SI unit of power, defined as one joule per second. It measures the rate of energy transfer or conversion. Watts are used universally for measuring electrical power, light output, and heat generation.
History
The watt is named after Scottish engineer James Watt, who made significant improvements to the steam engine. It was adopted as the SI unit of power in 1882 by the Second Congress of the British Association for the Advancement of Science.
