Convert kilovolt ampere to attojoule/second
Please provide values below to convert kilovolt ampere [kV*A] to attojoule/second [aJ/s], or Convert attojoule/second to kilovolt ampere.
How to Convert Kilovolt Ampere to Attojoule/second
1 kV*A = 1e+21 aJ/s
Example: convert 15 kV*A to aJ/s:
15 kV*A = 15 × 1e+21 aJ/s = 1.5e+22 aJ/s

Kilovolt Ampere
A kilovolt ampere (kV·A) is a unit of apparent power in an electrical circuit, equal to 1,000 volt-amperes, representing the product of voltage in kilovolts and current in amperes.
History/Origin
The kilovolt ampere emerged as a standard unit for measuring apparent power in electrical engineering, especially with the adoption of the SI system, to quantify the capacity of electrical equipment such as transformers and generators.
Current Use
Today, the kilovolt ampere is widely used in power systems to specify the capacity of electrical devices, particularly in the context of transformers, generators, and power distribution systems, facilitating the design and analysis of electrical networks.
Attojoule/second
An attojoule per second (aJ/s) is a unit of power representing the rate of energy transfer or conversion of one attojoule (10^-18 joules) per second.
History/Origin
The attojoule is a relatively recent SI prefix introduced to measure extremely small quantities of energy, and its use in power units like aJ/s has emerged with advancements in nanotechnology and quantum physics, though it remains a specialized unit with limited historical usage.
Current Use
The aJ/s is used in scientific research involving extremely low power measurements, such as in quantum physics, nanotechnology, and energy transfer studies at the atomic or molecular scale.
