Determine the number of tons you will be converting to watts. This will be the number you multiply by to obtain your result.
Multiply the number of tons by 3,517.2. So if you are converting 5 tons to watts, multiply 5 by 3,517.2 for a result of 17586 watts.
Convert watts into a smaller, more manageable kilowatt number by moving the decimal place over three places. Your answer would be 3.5172 kilowatts. Both watts and kilowatts are acceptable terms to express heat energy.
