Watt is a unit of power, within electrical systems wattage corresponds to the amount of power that an electric device uses per second.
Volt is a measurement of voltage, volts represent the electrical potential difference or pressure.
Ampere or amp is a measurement of electrical current, amps represent the rate at which electricity flows.
Ohms is a unit of electrical resistance, the greater the ohms the more difficult it is for current to flow.
Watt calculation/conversion formulas:
watts = volts² / ohms
watts = amps² * ohms
watts = volts * amps
Volt calculation/conversion formulas:
volts = √ watts * ohms
volts = watts / amps
volts = amps * ohms
Amp calculation/conversion formulas:
amps = volts / ohms
amps = watts / volts
amps = √ watts / ohms
Ohms calculation/conversion formulas:
ohms = volts / amps
ohms = volts² / watts
ohms = watts / amps²
