Reactive Energy Unit Conversion

Volt-ampere reactive hour (VARh) represents the accumulation of reactive power over one hour. Specifically, 1 var-hour represents 1 var of reactive power sustained for 1 hour (1 varh = 1 var × 1 hour). Reactive energy is commonly used to describe reactive power in AC systems, such as in the calculation and compensation of reactive power losses by power companies.

Millivolt-ampere reactive hour (mVARh) represents one-thousandth of a var-hour. Specifically, 1 millivar-hour equals 0.001 var-hours (1 mvarh = 0.001 varh). Millivar-hours are often used to describe smaller amounts of reactive energy, such as the reactive power in small electronic devices or localized power systems.

Kilovolt-ampere reactive hour (kVARh) represents 1,000 var-hours. Specifically, 1 kilovar-hour equals 1,000 var-hours (1 kvarh = 1,000 varh). Kilovar-hours are commonly used to describe medium-scale reactive energy, such as the reactive power in industrial equipment and commercial buildings.

Megavolt-ampere reactive hour (MVARh) represents 1 million var-hours. Specifically, 1 megavar-hour equals 1 million var-hours (1 Mvarh = 1,000,000 varh). Megavar-hours are often used to describe large-scale reactive energy, such as the reactive power in large power systems and power plants.

Gigavolt-ampere reactive hour (GVARh) represents 1 billion var-hours. Specifically, 1 gigavar-hour equals 1 billion var-hours (1 Gvarh = 1,000,000,000 varh). Gigavar-hours are used to describe extremely large-scale reactive energy, such as the reactive power in entire power grids or transnational power systems.
