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 Volts to Watts Calculation:

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

For example, let’s convert 24 volts to watts for a DC Line circuit with 5 amps of current.

P(W) = V(V) x I(A)
P(W) = 24 x 5
P(W) = 120 W

### AC Single Phase Watts to Amps 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, let’s convert 220 volts to watts for an AC electrical circuit with 20 amps of current and a power factor of 0.9.

P(W) = Pf x V(V) x I(A)
P(W) = 0.9 x 220 x 20
P(W) = 3960 W

### 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 convert 440 Volts to watts for an AC Electrical circuit with 15 amps of current and a power factor of 0.8.

P(W) = √3 x pf x I(A) x V(V)
P(W) = √3 x 0.8 x 15 x 440
P(W) = 9145 W

### 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 convert 440 Volts to watts for an AC Electrical circuit with 10 amps of current and a power factor of 0.9.
P(W) = 3 x pf x I(A) x V(V)
P(W) = 3 x 0.9 x 10 x 440
P(W) = 11880 W

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 220V in watts?

220V refers to voltage. A watt is a unit that expresses Real power, according to Real power = voltage × current, so if the current is 20A, the power corresponding to the voltage of 220V is 4400W.

How to calculate volts?

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

Difference Between Watts and Volts

differences between watts and volts are given here in detail. Both volts and watts are related to each other. 1 watt is defined as the energy required by 1 ampere of current to flow through the potential difference of 1 volt.

How to find wattage?

Amps multiplied by Volts equals Watts, which is the measurement used to determine the amount of energy. The higher the wattage is, the more Real power and output from the appliance.

What is a Watts calculator?

How do you calculate watts? - Watt's equation. Our calculator is based on the 2 laws that describe simple electrical circuits. 1 of them - Watt's law - states that: Power = Voltage * Current - in symbols: P = V * I.
