🧮 Coil Building Calculator — wraps, resistance & battery safety

Coil Building Calculator

Plan the build before you spool off wire. Pick your wire and target resistance to get the wrap count, the wire length to cut, and how hard the coil pulls on your battery.

Coil wrap calculator

— wraps per coil
—wire to cut
—build resistance
—amps at 4.2 V

Wrap counts assume 5 mm legs and round to the nearest half wrap. Always check the real build with an ohm reader before you fire it — and a coiling jig keeps the wraps tight and even.

Ohm’s law

Enter any two values — the other two fill in. Mostly matters on mechanical/unregulated mods, where coil resistance sets battery draw directly.

Building something exotic — twisted, ribbon, staged heat flux? Steam Engine is the deep-dive tool; our numbers use the same wire data, so they agree.

Rebuildables are for experienced vapers. Amp guidance uses bench-tested continuous ratings, not the numbers printed on battery wraps, and assumes a fresh 4.2 V cell on a mechanical mod — the worst case you have to build for. When in doubt, build higher resistance.
