Under the International System of Units (SI) and ISO 80000-5, the Joule (symbol: J) is defined as the amount of work exerted when a force of one newton displaces an object by one meter in the direction of the force ($1\text{ J} = 1\text{ N}\cdot\text{m}$). Electrically, it equals the heat dissipated when a constant electric current of one ampere passes through a resistance of one ohm for one second ($1\text{ J} = 1\text{ W}\cdot\text{s}$). In fundamental base units: $1\text{ J} = 1\text{ kg}\cdot\text{m}^2/\text{s}^2$.

A physical or thermochemical calorie (small 'c') is the energy required to raise the temperature of 1 gram of air-free water by 1°C at standard atmospheric pressure, standardized to exactly 4.184 Joules. On consumer food nutrition panels, "Calories" (often capitalized as Calorie or large Calorie) are technically Kilocalories (kcal). Thus, a food item rated at 250 Calories contains 250,000 physical calories, which equals 1,046,000 Joules (1.046 Megajoules) of chemical potential energy.

Electrical power is the rate of energy transfer measured in Watts (Joules per second). Because the second is too granular for billing consumer electricity over months, utilities multiply power in kilowatts (1,000 W) by operating time in hours (3,600 s). Hence: $1\text{ kWh} = 1,000\text{ W} \times 3,600\text{ s} = 3,600,000\text{ Joules} = 3.6\text{ Megajoules}$. A 1,000W appliance running for one hour consumes exactly 1 kWh.

Albert Einstein's special theory of relativity established that mass and energy are interchangeable manifestations of the same physical property: $E = mc^2$. Because the speed of light squared ($c^2 \approx 8.98755 \times 10^{16}\text{ m}^2/\text{s}^2$) is immense, 1 single gram of pure matter converted completely to electromagnetic radiation releases approximately $89.88\text{ Terajoules}$—equivalent to roughly 21.5 kilotons of TNT explosive force.
