Use the calculator below to estimate electricity usage and cost based on the power requirements and usage of appliances. The amount of time and power that each appliance is used varies significantly between households, so for the best results, adjust the usage for each appliance to most accurately reflect your personal usage.
This calculator will determine the instantaneous energy, sustained energy, and power consumed by an electrical system given two of the three electrical parameters (voltage, current, or resistance) and the time.
Simple calculator for Work, Power, or Time. Just enter in your values.
Make use of this calculator to convert real power in watts to energy in joules. Simply enter both values - power in watts and time in seconds - into their respective text fields before clicking "Calculate".
Joules calculator helps you calculate the amount of kinetic energy an object has when it is in a moving position. You just need to put in how heavy an object is and how fast it’s going. A joule is a standard unit for energy in the International System of Units (SI).
Free online energy converter - converts between 55 units of energy, including joule [J], kilojoule [kJ], kilowatt-hour [kW*h], watt-hour [W*h], etc. Also, explore many other unit converters or learn more about energy unit conversions.
