Convert joule to kilowatt-second
joule
Definition: A joule (symbol: J) is a derived unit of energy in the International System of Units (SI). It is defined as the energy transferred to an object when a one newton force is applied to the object in the direction of its motion through a distance of one meter. It is also defined as the energy dissipated as heat when a 1 ampere electric current passes through a resistance of one ohm in the course of one second. It has a number of representations both in SI base units as well as other SI units such that:
History/origin: The unit, joule, is named after James Prescott Joule, an English physicist and mathematician who helped develop the Kelvin scale. He also discovered the relationship between heat and mechanical work, leading to the law of conservation of energy, and subsequently, the first law of thermodynamics.
Current use: As an SI derived unit, the joule is used within a variety of scientific contexts. Practical examples of energy measurement using joules include the energy required to lift objects, the energy released when objects fall, the heat required to raise temperature, and the kinetic energy of moving objects.
kilowatt-second
Definition: Kilowatt-second is a measure of energy, work, or heat. For conversion purposes, its value is 1000 times the reference unit, joule.

How to Convert joule to kilowatt-second
1 joule = 0.001000 kilowatt-second
1 kilowatt-second = 1000 joule
Example
Convert 15 joule to kilowatt-second:
15 joule = 15 × 0.001000 kilowatt-second = 0.015000 kilowatt-second
