Reverse All Units

Converting between calories and watt-hours is essential in physics, nutrition, electrical engineering, and heating calculations. Energy units bridge different domains: joules in physics, calories in nutrition, kilowatt-hours in electricity, and BTUs in heating.

Also convert to: J kJ MJ kcal Wh kWh BTU

0 cal = 0 wh

0 (zero) calorie(s) is equal to 0 (zero) watt-hour(s)

What is calorie?

The calorie (cal) equals 4.184 joules. It was originally defined as the energy needed to raise one gram of water by one degree Celsius. Small calories are used in chemistry and physics.

What is watt-hour?

The watt-hour (Wh) equals 3,600 joules. It measures electrical energy consumption over time. Battery capacities for small devices are often measured in watt-hours.
