Energy Units and Conversions

Energy Units and Conversions. Power = Current x Voltage (P = I V) 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts. 1 kilowatt-hour is the energy of one kilowatt power flowing for one hour. (E = P t). 1 kilowatt-hour (kWh) = 3.6 x 10 6 J = 3.6 million Joules.

Calories (cal)

A calorie (or thermochemical calorie) is a unit of energy in the International System of Units (SI). The symbol for calorie is cal. A calorie is measured as the quantity of heat required to raise the temperature of 1 gram of water by 1°C from a standard initial temperature at a pressure of 1 atmosphere. A calorie is also called a small calorie or gram calorie.

1.7.1 Energy | CIE IGCSE Physics Revision Notes 2022

Energy is the capacity of something to do work: If something contains a store of energy it is able to do work. If something does not store energy then it will not work. The law of conservation of energy states that: Energy cannot be created or destroyed, it can only change from one form to another. What this means is that the total amount of ...
