### FAQ's & How to

#### How to calculate Watts

To calculate Watts we use the following formula:

SINGLE PHASE

• Watts = Amps x Volts

For example, if Amps = 10 and Volts = 110 then,

10 (A) x 110 (V) = 1100 Watts.

#### How to calculate Amps

To calculate Amps we use the following formula:

SINGLE PHASE

• Amps = Watts ÷ Volts

For example, if Watts = 3000 and Volts = 110 then,

3000 (W)  ÷ 110 (V) = 27.27 Amps.

#### How to calculate Volts

To calculate Volts we use the following formula:

SINGLE PHASE

• Volts = Watts ÷ Amps

For example, if Watts = 3000 and Amps = 13 then,

3000 (W) ÷ 13 (A) = 230.76 Volts.

#### How to calculate kW

To calculate kW from Amps we use the following formula:

SINGLE PHASE

• kW = Amps x Volts ÷ 1000

For example, if Amps = 25 and Volts = 110 then

25 (A) x 110 (V) = 2750 (W) ÷ 1000 = 2.75 kW.

#### How to calculate Power Factor

There are a number of methods to calculate Power Factor, the method to use depends on the information you have and the outcome you require, this Watts Amps Volts Calculator can calculate Power Factor from kW, Amps and Voltage (Three Phase).

To directly convert kW or kVA to or from Power Factor our kVA Calculator could be a great addition to your collection of electrical calculators, view » kVA Calculator.

#### How to convert kW to kVA

To convert from kW to kVA or from kVA to kW you can use the dedicated kVA Calculator App, view » kVA Calculator.

#### Watts Amps Volts Formula

The formula for Watts Amps Volts conversion is based on the Ohm’s Law triangle V over IR.

• V = Volts
• I = Current
• R = Resistance

We also have a dedicated Ohm’s Law App which is a great addition to the Watts Amps Volts Calculator.

#### Watts Amps Volts Conversion Calculator

With this Watts Amps Volts Calculator you can use it for converting any of the following,

Single Phase Watts Amps Volts Conversion:

• Watts (W)
• Amps (A)
• Volts (V)

Three Phase kW Amps Volts Power Factor Conversion:

• kW (kiloWatt)
