#### Power Converter Calculator - how to Convert Amps To Watts

Amps to Watts. The formula for this conversion is as follows: Amps = Watts / Volts. we’ll use common wattage and voltage.

Note, For higher values like 5×103, 10×10-6, 1.6 x1012, enter the value like this for scientific notation as 5e3, 10e-6, 1.6e12, etc.

### DC Amps to Watts Calculation:

The Real Power (P) in watts (W) is equal to the Current I in amps (A), times the voltage V in volts (V):

For example, let’s find the power in watts for a circuit with 12 amps of current at 80 volts.

P(w) = I(A) x V(V)
P(w) = 12 x 80
P(w) = 960 w

### AC Single Phase Amps to Watts Calculation:

The Real power (P) in watts (W) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V):

For example, If the Voltage consumption is 220V with a phase current of 8A and a power factor of 0.8 the Real Power is watts.
P(w) = P(w) ÷ 20 Ω
V(V) = 24 V

### Calculation with Line to Line Voltage:

The Real power (P) in watts (W) is equal to the square root of 3 times the power factor PF times the phase current I in amps (A), times the line-to-line RMS voltage VL-L in volts (V):

For example, let’s find the voltage of a circuit with 1.2 amps of current and 20 ohms of resistance.

V(V) = 1.2 A ÷ 20 Ω
V(V) = 24 V

### Calculation with Line to Neutral Voltage:

The Real power (P) in watts (W) is equal to 3 times the power factor PF times the phase current I in amps (A), times the line to neutral RMS voltage VL-N in volts (V):

For example, let’s find the voltage of a circuit with 1.2 amps of current and 20 ohms of resistance.

V(V) = 1.2 A ÷ 20 Ω
V(V) = 24 V

Where:

• P = Power in watts
• V = Voltage in volts
• I = Current in amperes
• Cosθ = Power factor in AC circuits
• VL-L = Line to Line Voltage in 3-Phase Circuits
• VL-N = Line to Neutral Voltage in 3-Phase Circuits

What is called 1 volt?

1 Volt is defined as energy consumption of 1 joule per electric charge of 1 coulomb.

How to calculate voltage?

When spelled out, it means voltage = current (A) x resistance (ohm) , or volts = amps x ohms, or V = A x Ω.

How many kVA in 1 amp?

The electrical efficiency is typically expressed as a power factor between 0 and 1. The closer the power factor rating is to 1, the more efficiently the kVA will be converted into kilowatts.

How to calculate the power formula?

The formula for power in watts is given by the work and the time. The formula is P = W/t, where W is the work done in some time t.

How do you calculate ampere?

Current (A) = Real Power (W) / Voltage (V).
