We know that Amps or Ampere (A) is a unit of flowing Electric Current. It can be stated as “The Rate of Electric Charge flow with respect to Time”. In physics perspective one Amps (or) one Ampere (A) is equal to one Coulomb (Q) per Second (S). By the way Watt (W) is the unit of Power in electric measurement. It can be defined as “The Power is the rate of Energy usage with respect to Time”. In physics perspective one Watt (W) is equal to one Jule (J) per second (S). In the following simple Amps to Watts conversion calculator you can calculate Simple DC Power, AC Single Phase Power and AC Three Phase Power.
Amps to Watts Calculator
What is Watt (W)?
The watt is named after engineer James Watt. In electrical power watt can be calculated in the following ways.
P = V * I
Power (P) = Voltage (V) * Current (I)
As per this formula the total Power of any circuit is equal to the product of total Voltage and Current of the circuit.
If you want to calculate the power using Resistance value then you can use
Here, R = Resistance in ohms.
DC supply Amps to Watts
In this calculator Simple Power calculation and Advanced DC supply Amps to Watts calculation are done by the following formul.
P = V * I (Watts)
AC Supply Amps to Watts
For AC power systems, the power calculation depends on the type of phase ( AC Single Phase, or AC Three Phase). Choose the Phase option as AC Single phase to calculate the power. This calculator used the following formula to calculate power of single phase AC supply.
P = I * V * PF
P(Watts)=I(Current in Amps) * V(Voltage in Volts) * Power Factor
AC Three Phase
For AC Three Phase you have to choose the voltage type as either Line to Line Voltage or Line to Neutral Voltage.
