A measure of the amount of electric charge passing a point in an electric circuit per unit time with one coulomb per second.

One ampere is equal to 1000000 or 10-6 microamperes.

Symbol representation is A or Amp.


The ampere unit is named after Andre-Marie Ampere, from France.

How to Convert Amps to Volts

Voltage is the potential difference in an electrical circuit, measured in volts. It might be easier to think of it as the amount of force or pressure pushing electrons through a conductor. To convert amps to volts we can use a simple formula defined by Watt’s Law.

Per Watt’s Law, voltage is equal to power divided by current.
Voltage(V) = Power(W) ÷ Current(A)

Formulas to Calculate Amps
Solve for current using these formulas:
Current = Voltage ÷ Resistance
Current = Power ÷ Voltage
Current = √Power ÷ Resistance
