The normal calculations for watts are as follows.
amps x volts = watts
volts2 / ohms = watts
amps2 x ohms = watts

To calculate the watts in 16kV, you would need to know the current flowing through the circuit. The formula to calculate watts is Watts = Volts x Amps. Without the value of current (Amps), we cannot determine the watts.

Divide Watts by Volts ; this gives you Amps.
You can calculate amperage (A) using the formula A = W / V, where W is the power in watts and V is the voltage. Simply divide the power in watts by the voltage to find the amperage.
To calculate watts you need two of the three: Voltage (V), Current (A) and Resistance (ohm). Power (Watts) = (V^2) / R = (I^2)R = VI
To calculate watts in cycling, you multiply your current power output (in watts) by your pedaling cadence (in revolutions per minute). This formula helps determine the amount of energy you are generating while cycling.
To calculate watts when cycling, you multiply your current power output in watts by your pedaling cadence in revolutions per minute (RPM). This formula helps you measure the amount of energy you are producing while cycling.
To calculate the power in watts, you will also need to know the current in amperes. The formula to calculate power is P (watts) = V (volts) x I (amperes). If you only have the voltage (30 volts) and not the current, you cannot determine the power in watts.
Try 746 watts = 1 HP
To calculate the watts from amps, you need to know the voltage of the circuit. The formula to calculate watts is: Watts = Amps x Volts. So, without knowing the voltage in the circuit, it is not possible to accurately determine the wattage from just knowing the amperage.
You should not have to calculate the watts of the unit. All the information that you need will be on the nameplate of the unit. It is this information that electricians use to calculate the conductor size and breaker to supply the power to the unit.
