Enter the total watts (W), the total time (hr), and the cost per watt-hour ($/WH) into the Watt to Cost Calculator. The calculator will evaluate and display the Watt to Cost. ## Watt to Cost Formula The following formula is used to calculate the Watt to Cost. WTC = W * T * CPW • Where WTC is the Watt to Cost ($)
• W is the total watts (W)
• T is the total time (hr)
• CPW is the cost per watt-hour ($/WH) ## How to Calculate Watt to Cost? The following example problems outline how to calculate Watt to Cost. Example Problem #1 1. First, determine the total watts (W). The total watts (W) is given as 5000 . 2. Next, determine the total time (hr). The total time (hr) is calculated as 3 . 3. Next, determine the cost per watt-hour ($/WH). The cost per watt-hour ($/WH) is found to be .25. 4. Finally, calculate the Watt to Cost using the formula above: WTC = W * T * CPW Inserting the values from above yields: WTC = 5000 * 3 * .25 = 3,750.00 ($)

Example Problem #2

The variables needed for this problem are provided below:

total watts (W) = 7000

total time (hr) = 8

cost per watt-hour ($/WH) = .10 Entering these values and solving gives: WTC = 7000 * 8 * .10 = 5,600.00 ($)
