To Properly use this calculator to build a .3ohm coil with a low heat flux on an Atlantis aspire, i first go to wattage on heatflux and then put in 58.8 watts (this is the number i get for .3ohms at 4.2 volts) I then put in .3 ohms for target resistance. Now i just go and change the wire and gauge settings until i have something with a heatflux between 20-30 and wraps under say 15. Is this the correct way to use this calculator for what i am trying to do? I am just trying to figure out what wire material and gauge to purchase, and then how many wraps i ideally want to do.
