Kilowatt Hours to Joules Conversion
Converting Kilowatt Hours (kWh) to Joules (J) is a common energy and power conversion. 1 kWh equals 3,600,000 J. For example, 100 kWh is equal to 360,000,000 J.
Quick Mental Math: Kilowatt Hours to Joules
Multiply kilowatt-hours by 3.599.997 to convert to joules.
Why is converting Kilowatt Hours to Joules tricky?
kilowatt-hours to joules mixes food calories (kilocalories) with scientific calories.
Quick Reference Values
1 kWh = 3,600,000 J. 5 kWh = 18,000,000 J. 10 kWh = 36,000,000 J. 25 kWh = 90,000,000 J. 50 kWh = 180,000,000 J. 100 kWh = 360,000,000 J.
What is Kilowatt Hours?
Kilowatt Hours (kWh) is a unit of energy and power. A kilowatt-hour (kWh) measures electrical energy equivalent to one kilowatt of power supplied for one hour. It equals 3.6 million joules and is the standard billing unit for electricity consumption worldwide [bipm-si-brochure]. The kilowatt-hour emerged with widespread electric power usage in the late 19th and early 20th centuries. It became standardized as electric utilities adopted it for consumer energy measurement and billing [bipm-si-brochure]. The kWh is the universal unit for residential and commercial electricity billing globally, including in North America, Europe, and Asia. It is used extensively in energy management, engineering, and environmental reporting [nist-si-guide].
What is Joules?
Joules (J) is a unit of energy and power. The joule is the SI unit of energy defined as the work done when a force of one newton moves an object one meter in the direction of the force. It equals one kilogram meter squared per second squared (kg·m²/s²). This definition aligns with the International System of Units as standardized by the BIPM [bipm-si-brochure]. The joule is named after James Prescott Joule, a 19th-century physicist who studied energy conservation. It was officially adopted as a unit of energy by the CGPM in 1948 to unify energy measurement standards internationally [cgpm-resolutions]. Joules are used worldwide in physics, engineering, and electrical industries to quantify energy, work, and heat. Countries using the SI system, including those in Europe, Asia, and the Americas, rely on joules for scientific and industrial applications [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: kilowatt hour, kw/h, kwh, kilowatthour, joule, joul, jouls, juls. All of these refer to the Kilowatt Hours to Joules conversion.
