Edit: My bad.. steam-engine does actually give the same results. But I do like the set up of this one a bit more. Watts/Volts/Amps/Ohms conversion calculator Here is an example. (EXAMPLE ONLY!) Enter watts: ?? Enter volts: 3.7 Enter amps: ?? Enter ohms:0.05 Calculate: Enter watts: 273.8 Enter volts: 3.7 Enter amps: 74 Enter ohms:0.05 Results are in bold. Now as i said, this is an example. It is up to you to know what your battery and mods can handle. Personally, I wouldn't even attempt to build at 0.05 ohms. I am not that advanced or comfortable with my mech yet. I probably will never go lower than a 0.08ohm. For now, I am sticking my wussy butt around the 0.15 ohm mark and parking it there. And I will say it a 3rd time..this is for more accurate readings, be it at 0.52 ohm or 0.15 or 0.17 ohm, and super sub ohm building is for advanced builders only! This will however help new people see the relation between amps, ohms, volts, and watts. Best part, you can play with the values without blowing your face off.
