Convert joule/hour to volt ampere
Please provide values below to convert joule/hour [J/h] to volt ampere [V*A], or Convert volt ampere to joule/hour.
1 J/h = 0.000277778 V*A. To convert joule/hour to volt ampere, multiply the value by 0.000277778; to go the other way, divide by it (1 V*A = 3599.99712 J/h). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 J/h = 0.000277778 V*A

Joule/hour
A joule per hour (J/h) is a unit of power representing the amount of energy (in joules) transferred or converted per hour.
History/Origin
The joule per hour has been used as a measure of power in various scientific and engineering contexts, especially where energy transfer rates are expressed over longer periods. It is derived from the SI unit of energy, the joule, divided by time in hours.
Current Use
Joule per hour is occasionally used in fields like heating, energy consumption, and industrial processes to quantify power over extended durations, though it is less common than watts for standard power measurements.
Volt Ampere
Volt ampere (V·A) is a unit of apparent power in an electrical circuit, representing the product of voltage and current without considering power factor.
History/Origin
The volt ampere was established as a unit of apparent power with the development of electrical engineering, particularly as a measure in alternating current (AC) systems. It is derived from the SI units volt (V) and ampere (A).
Current Use
Volt ampere is used to quantify apparent power in AC electrical systems, especially in the context of transformers, generators, and power supplies, to assess capacity and performance.
