Convert watt-second to kilojoule
watt-second
Definition: Watt-second is a measure of energy, work, or heat. For conversion purposes, its value is 1 times the reference unit, joule.
kilojoule
Definition: The kilojoule is an SI (International System of Units) derived unit of energy that is equal to 1000 joules. The joule is defined as the amount of energy transferred to an object when a one newton force acts on an object in the direction movement through a distance of one meter.
History/origin: The kilojoule, like other SI derived units, uses SI prefixes to denote multiples or submultiples of the given unit. In this case, the prefix "kilo" is used to express a multiple of 1000.
Current use: In countries that have adopted SI, the kilojoule is widely used as a unit of food energy. In some cases, both kilojoules and kilocalories are displayed, though in countries such as the United States, only kilocalories are shown (often referred to as "Calories") on food labels. Aside from this everyday use, kilojoules are used within scientific contexts around the world.

How to Convert watt-second to kilojoule
1 watt-second = 0.001000 kilojoule
1 kilojoule = 1000 watt-second
Example
Convert 15 watt-second to kilojoule:
15 watt-second = 15 × 0.001000 kilojoule = 0.015000 kilojoule
