What is Watt-hour?

The watt-hour is a unit of energy equal to 3,600 joules, representing the energy used by one watt of power over one hour. It is commonly used for portable battery capacities; a typical power bank rated at 5,000 mAh at 3.7 V holds about 18.5 Wh. Airline regulations for lithium-ion batteries are also specified in watt-hours, with batteries under 100 Wh generally permitted in carry-on luggage.

What is Kilocalorie?

The kilocalorie equals 1,000 thermochemical calories and is the standard unit for food energy labeling in Japan, the United States, and many other countries. It is often written as "Cal" (with a capital C) or simply called a "Calorie" on food packages. A bowl of rice (150 grams) contains about 235 kcal, a slice of bread about 160 kcal, and 30 minutes of walking burns roughly 100 kcal.
