Watts-volts-amps-ohms calculator

Watts-volts-amps-ohms calculator

It is a conversion calculator that is used to compute the voltage, power, current and resistance. Unlike most online calculators it performs multiple conversion at once. It is simple to use and requires you to enter any two known values to determine the other unknown units.

Once you have two of the cells filled with correct figures, click on the ‘Calculate' button for the converter to calculate the results of the two unknown values. If you have entered wrong values or you want to perform new conversions, the ‘Reset' button is useful erasing all the data in the respective fields.

Formula for calculating the Ohms

R = V/I, which means that the resistance in ohms (Ω) is calculated by dividing the volts by the current in amps.

R = V2/P, which means that the resistance in ohms (Ω) is calculated by dividing the squared voltage in volts by the power in watts.

R = P/I2, which means that the resistance in ohms (Ω) is calculated by dividing the power in watts by the squared current in Amps.

Formula for calculating Volts

V = I x R, which means that the voltage in volts is computed by the multiplication of current in amps with the resistance in ohms.

V = P/I, where the voltage is volts is calculated by dividing the power in watts by the current in amps.

V = √P x √R, where the voltage in volts is calculated by the square root of power in watts by the resistance in ohms.

Formula for calculating Amps

I = V/R, which means that the current in amps is computed by dividing the voltage in volts by the resistance in ohms.

I = √P/R, where the current in Amps is calculated by multiplying the square root of power in watts dividing it by the resistance in ohms.

Formula for calculating Watts

P = I2 x R, which means that the power in watts is calculated by multiplying the squared current in amps by the resistance in ohms.

P = V x I, where the power in watts is computed by multiplying the volts by the current in amps.
