About this tool
Calculate electrical power, current, voltage or energy for a simple DC/single-phase load. Use the form above to enter Voltage (V), Current (A), Power factor, Runtime (hours). The calculation or transformation runs locally in your browser.
Method
For the simple single-phase estimate, apparent power = V × I and real power = V × I × power factor. Energy = real power × time.
