It is a conversion calculator which converts the energy from Kilowatt-hours and time in hours to Power in watts. It has two text fields which require you to enter the power in kilowatt-hours and the time in hours respectively. Below the text fields are the Calculate and Reset buttons which perform different functions.

The Calculate button is used to execute the conversion in a single click. The calculator is fast in its operations and only requires you to enter the right units in the appropriate cells. It is always difficult for an individual to perform calculations manually especially when they are many. The converter reduces the tedious paperwork and saves time when converting kWh to Watts.

The power P in watts (W) is equal to 1000 times the energy E in kilowatt-hours (kWh),

P_(W) = 1000 × E_(kWh) / t_(hr)
