## How to Convert Amperes to Megaamperes

To convert a measurement in amperes to a measurement in megaamperes, divide the electric current by the following conversion ratio: 1,000,000 amperes/megaampere.

Since one megaampere is equal to 1,000,000 amperes, you can use this simple formula to convert:

megaamperes = amperes ÷ 1,000,000

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

**For example,**here's how to convert 5,000,000 amperes to megaamperes using the formula above.

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

## What Is an Ampere?

The ampere, commonly referred to as an "amp," is the electrical current constant equal to the flow of one coulomb per second.

The ampere was previously defined as a constant current that when passed 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.

In 2019, the ampere was redefined as the electric current corresponding to the flow of 1/(1.602 176 634 × 10^{-19}) elementary charges per second.^{[1]}

The ampere is the SI base unit for electric current in the metric system. An 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.

### Amperage and Ohm's Law

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.

I_{A} = V_{V} / R_{Ω}

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

## What Is a Megaampere?

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 millions, or 10^{6}. 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.
