If this formula does not give you a number you believe (like 10% off any
"standard wattage") don't sweat it. The resistance of the heating element
must be measured while carrying the full current to give an accurate value.
The "cold " resistance is not the same as when it is hot and drawing power.
Just pick the closest "standard" power level and it will probably be the
correct value for the heater. If you want a closer number, try to measuer
the resistance of the plug (after you pull it from the socket) before it
