How to Convert Statamperes to Amperes

To convert a measurement in statamperes to a measurement in amperes, multiply the electric current by the following conversion ratio: 3.3356E-9 amperes/statampere.

Since one statampere is equal to 3.3356E-9 amperes, you can use this simple formula to convert:

amperes = statamperes × 3.3356E-9

The electric current in amperes is equal to the electric current in statamperes multiplied by 3.3356E-9.

For example, here's how to convert 500,000,000 statamperes to amperes using the formula above.
amperes = (500,000,000 statA × 3.3356E-9) = 1.667821 A

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

What Is a Statampere?

The statmpere is the electrical current constant equal to the flow of one statcoulomb per second, or 0.33356 nanoamperes in the International System of Units.

The statampere is a centimeter-gram-second (CGS) electrostatic unit of electric current. Statamperes can be abbreviated as statA, and are also sometimes abbreviated as A-esu. For example, 1 statampere can be written as 1 statA or 1 A-esu.

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.

IA = VV / R

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