Milli-Amps (ma) from Volts Calculator

Formula

The formula to calculate the milli-amps (ma) from volts is:

$ma = \frac{P}{V} \times 1000$

Where:

ma is the milli-amps of current
P is the power (watts)
V is the voltage (volts)

What is Volts to ma?

Volts are a measure of voltage and ma stands for milli-amps, which is a measure of current. These two are related through the equation $P = I \times V$ , where $P$ is power, $I$ is current, and $V$ is voltage. To calculate milli-amps from volts, divide the power by the voltage, then multiply by 1000.

Example Calculation

Example 1:

Power: 10 watts
Voltage: 5 volts

Calculation:

$ma = \frac{10}{5} \times 1000 = 2000 \text{ mA}$

Example 2:

Power: 15 watts
Voltage: 3 volts

Calculation:

$ma = \frac{15}{3} \times 1000 = 5000 \text{ mA}$
