History

Kilowatt Hour (kWh)

The kilowatt-hour, symbolized as kWh, is a common unit in electricity billing and energy reporting. It is the energy used by a 1-kilowatt device for 1 hour, or 3.6 million joules. With the advent of electrification in the late 1800s and early 1900s, the kilowatt-hour made measuring electrical energy simpler for both utilities and customers. Its use is crucial for billing, energy management, and understanding electricity use in homes, industry, and renewable energy.

Joule (J)

The joule (J), recognized as the SI unit of energy, is named in honor of physicist James Prescott Joule. It represents the amount of work performed when a force of one newton moves an object over a distance of one meter. The joule is widely used in physics, thermodynamics, and engineering, providing a standardized way to quantify energy across mechanical, electrical, and thermal processes. Its implementation has enabled researchers and professionals to measure and compare energy values with accuracy and consistency around the globe.
