How the formula works
Both volt and milliampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in volts by 1000 to get milliamperes. To reverse the conversion, multiply a milliampere value by 0.001 to get back to volts.
Frequently asked questions
What is Volt (V)?
The volt (V) is the SI unit of electric potential difference, the "push" that drives current through a circuit.
What is Milliampere (mA)?
A Milliampere (mA) equals 1/1,000 ampere(s), a scaled unit of electric current used for milli-scale electrical work.
How do I convert volts to milliamperes?
Multiply the volt value by 1000 to get the equivalent in milliamperes. For example, 5 V × 1000 = 5000 mA.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1000 is an exact, non-rounded value.
Can I convert milliamperes back to volts?
Yes. Divide the milliampere value by 1000, or multiply it by 0.001, to get volts.
