How to Convert Megaamperes to Amperes

To convert a megaampere measurement to a ampere measurement, multiply the electric current by the conversion ratio. One megaampere is equal to 1,000,000 amperes, so use this simple formula to convert:

amperes = megaamperes × 1,000,000

The electric current in amperes is equal to the megaamperes multiplied by 1,000,000.

For example, here's how to convert 5 megaamperes to amperes using the formula above.
5 MA = (5 × 1,000,000) = 5,000,000 A

Megaamperes and amperes are both units used to measure electric current. Keep reading to learn more about each unit of measure.


One megaampere is equal to 1,000,000 amperes, which are the electrical current equal to the flow of one coulomb per second.

The megaampere is a multiple of the ampere, which is the SI base unit for electric current. In the metric system, "mega" is the prefix for 109. A megaampere is sometimes also referred to as a megaamp. Megaamperes can be abbreviated as MA, for example 1 megaampere can be written as 1 MA.


The ampere, commonly referred to as just "amp," is the electrical current constant equal to the flow of one coulomb per second. According to an SI brochure, the ampere is a constant current that when passsed through two straight and parallel conductors that are spaced one meter apart, will produce a force equal to 0.0000002 newtons per meter of length.

The ampere is the SI base unit for electric current in the metric system. A ampere is sometimes also referred to as an amp. Amperes can be abbreviated as A, for example 1 ampere can be written as 1 A.

Ohm's Law states the current between two points on a conductor is proportional to the voltage and inversely proportional to the resistance. Using Ohm's Law, it's possible to express the current in amperes as an expression using resistance and voltage.


The current in amperes is equal to the potential difference in volts divided by the resistance in ohms.
