Kilowatt-hours (kWh)

Definition

A kilowatt-hour (kWh) is a unit of energy equal to 1,000 watt-hours or 3,600,000 joules. It represents the energy consumed by a 1,000-watt appliance running for one hour.

History

The kilowatt-hour became the standard billing unit for electricity with the widespread electrification of homes and businesses in the early 20th century. Power utilities worldwide adopted it for metering.

Current use

Kilowatt-hours are the universal unit for residential and commercial electricity billing. They are also used to measure electric vehicle battery capacity, solar panel output, and grid-level energy storage.

Calories (cal)

Definition

A calorie (cal), also known as a small calorie or gram calorie, is defined as the amount of heat energy needed to raise the temperature of one gram of water by one degree Celsius. It equals approximately 4.184 joules.

History

The calorie was first defined by French chemist Nicolas Clément in 1824. It was widely used in chemistry and physiology before the joule became the official SI unit of energy.

Current use

Small calories are used in chemistry and physics for heat measurements. In everyday language, 'calorie' often refers to the kilocalorie (kcal) when discussing food energy.
