What is Calorie (thermochemical)?

The thermochemical calorie is a unit of energy originally defined as the amount needed to raise the temperature of one gram of water by one degree Celsius. It is exactly 4.184 joules. Note that the "Calorie" seen on food labels is actually a kilocalorie (1,000 calories). The calorie has deep roots in calorimetry and chemistry, and although the SI system favors joules, calories remain widely used in everyday discussions of food and diet.

What is Kilowatt-hour?

The kilowatt-hour equals 1,000 watt-hours and is the standard billing unit for household electricity. An average Japanese household uses about 300 kWh per month, and electricity costs roughly 25 to 40 yen per kWh. Electric vehicle batteries range from about 40 to 100 kWh, providing approximately 6 to 8 km of range per kWh. Solar panel output is also measured in kWh.
