# Milliamps to Amps and Amps to Milliamps: How Many Milliamps Are In An Amp?

Milliamps (mA) and amps (A) are directly related units of electric current, making the conversion from milliamps to amps and amps to milliamps very easy.

In order to convert milliamps to amps and amps to milliamps, feel free to use our conversion chart, conversion calculator, but also, learn the relationship between these units.

Just be aware that the "milli (m)" is one of the official unit prefixes in the International System (SI) of Units and means one-thousandth (1/1000 = 1/10^{3} = 10^{-3}) - so one milliamp (mA) is one-thousandth of one amp (A).

## Conversion Formulas

Both milliamps (mA) and amps (A) are units of electric power, with the following relation between them:

**1 Amp (A) = 1000 milliamps (mA)**

**1 milliamp (mA) = 1/1000 Amp = 0.001 Amp (A)**

Again, "milli (m)" is one of the official unit prefixes in the International System (SI) of Units and means one-thousandth (1/1000 = 1/10^{3} = 10^{-3}) - one milliamp is one-thousandth of an amp.

Thus, in order to convert the electric current given in milliamps into the electric current given in amps and vice versa, be sure to remember the following formulas:

**I _{amps} = I_{milliamps }/ 1000**

**I _{milliamps} = I_{amps }* 1000**

## Milliamps to Amps and Amps to Milliamps Conversion Examples

Using conversion formulas, it is fairly easy to convert milliamps to amps and amps to milliamps:

### 500 milliamps to amps:

**I _{(A)} = 500 milliamps / 1000 = 0.5 A**

### 3.675 amps to milliamps:

**I _{(mA)} = 3.675 Amps * 1000 = 3675 mA**

Milliamps are very small amounts of electric current measured with very accurate instruments.

**For example:**

CR2032 non-rechargeable 3V lithium button/coin cell battery is a very popular lithium battery with a nominal voltage of 3V, nominal capacity of 200-230mAh and is often used in remote control units, requiring the battery to provide relatively strong currents in very short periods of time.

In order to calculate the electric current of such a battery, we use the following formula:

**I(A) = U(V) / R(Ω) = 3V / 560 Ω = 0.005357 A = 5.357 mA**

So, when converting milliamps to Amps and Amps to milliamps, just be sure to multiply and divide by 1000, and generally, that is all.

Also, when converting microamps to milliamps and milliamps to microamps, again, just be sure to multiply and divide by 1000 - the simplicity of SI Unit prefixes.
