# Millivolts to volts and volts to Millivolts: How Many Millivolts Are In A volt?

Millivolts (mV) and volts (V) are directly related units of potential difference (Voltage), making the conversion from millivolts to volts and volts to millivolts very easy.

In order to convert millivolts to volts and volts to millivolts, 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 millivolt (mV) is one-thousandth of one volt (V).

## Millivolts to Volts and Volts to Millivolts Conversion Formulas

Both millivolts (mV) and volts (V) are units of potential difference - voltage, with the following relation between them:

**1 Volt (V) = 1000 millivolts (mV)**

**1 millivolt (mV) = 1/1000 Volt = 0.001 Volt (V)**

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 millivolt is one-thousandth of an volt.

Thus, in order to convert the voltage given in millivolts into the voltage given in volts and vice versa, be sure to remember the following formulas:

**U _{volts} = U_{millivolts }/ 1000**

**U _{millivolts} = U_{volts }* 1000**

## Millivolts to Volts and Volts to Millivolts Conversion Examples

Using conversion formulas, it is fairly easy to convert millivolts to volts and volts to millivolts:

### 500 millivolts to volts:

**U _{(V)} = 500 millivolts / 1000 = 0.5 V**

### 3.675 Volts to millivolts:

**U _{(mV)} = 3.675 Volts * 1000 = 3675 mV**

Millivolts are very small amounts of potential difference measured with very accurate instruments - a typical electronic multimeter can accurately measure the voltage down to 1 mV, with some models offering even greater accuracy.

**For example:**

Lead-acid starting batteries feature very low internal resistance, down to, or even less than 0.01Ω. When such battery is discharged with a certain current, a voltage drop appears across the battery terminals.

In order to calculate this voltage (potential difference) of such a battery, when the battery is being discharged with 30 Amps, we use the following formula:

**U(V) = I(A) * R(Ω) = 30A * 0.01Ω = 0.3 V = 300 mV**

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