Volt amperes are a unit used to describe the electrical load in engineering. Volt amperes can be abbreviated VA. You can also use metric prefixes such as "kilo-" and "mega-." It takes 1,000 volt amperes to equal one kilo-volt ampere and 1,000,000 volt amperes to equal one mega-volt ampere. Therefore, it takes 1,000 kilo-volt amperes to get one mega-volt ampere.
Divide the number of kVA by 1,000 to convert to MVA. For example, if you have 438 kVA, divide 438 by 1,000 to get 0.438 MVA.
Multiply the number of kVA by 0.001 to convert to MVA. In this example, multiply 438 by 0.001 to get 0.438 MVA.
