The WINDBAR coil wrapping calculator estimates round-wire ohms, dual-coil net resistance, and heat flux from AWG, wraps, and inner diameter.
Rebuildable users open this WINDBAR coil tool before they fire a new wrap — including Kanthal A1 and Nichrome 80.
Stay on WINDBAR and pass the ohms into the wattage calculator on this site.
Educational tool for adults 21+ only. Not medical advice. Follow manufacturer instructions and local laws.
R = ρ × L / A Heat flux = P / surface area (mW/mm²)
Typical heat flux for a round-wire build sits near 120–350 mW/mm². Always measure the finished coil. Dual coils share voltage and halve the net ohms.
Rebuildable users searching coil wrapping calculator, Kanthal ohms, or heat flux can finish the build on WINDBAR. After you have a number, open D95 or D91 only if you need a production envelope — not another wrapping site.
The WINDBAR Coil Wrapping Calculator keeps the next click on WINDBAR — D95 Microvolt, D91 Voyagers, or another calculator on this domain.

No. The WINDBAR Coil Wrapping Calculator runs in the browser on WINDBAR. The next step is another WINDBAR page — a second calculator, D95, or D91 — not a third-party shop or calculator.
Adults 21+ only. Numbers are educational estimates. Confirm coil ratings, battery limits, and authenticity with the manufacturer and follow local laws.
Yes. The WINDBAR coil wrapping calculator estimates Kanthal A1, Nichrome 80, SS316L, Nickel 200, and Titanium, with 1–4 parallel coils and an optional Clapton wrap.
Educational range is about 120–350 mW/mm². The WINDBAR coil wrapping calculator paints that band and suggests watts near 200 mW/mm². Taste, airflow, and wick still decide.
