How do you convert 400 millivolts to volts?

To convert millivolts to volts, you need to understand the relationship between these two units of measurement. One volt is equal to 1,000 millivolts. Therefore, to convert millivolts to volts, you can use the formula:

[

\text{Volts} = \frac{\text{Millivolts}}{1000}

]

In this case, when converting 400 millivolts to volts, you divide 400 by 1,000:

[

\text{Volts} = \frac{400}{1000} = 0.40 , \text{volts}

]

This confirms that the conversion is performed correctly, leading to the result of 0.40 volts, which is a correct interpretation of the measurement. It is important to keep in mind that if you don't perform the conversion correctly, you could easily misinterpret the magnitude of the voltage, affecting any related calculations or applications.
