FAQ
- What is a DIY e-liquid calculator?
- A planning tool for adults who mix their own e-liquid. Given a batch size, nicotine target, and PG/VG ratio, it calculates the planned amounts of nicotine base, flavoring, PG, and VG — in mL, grams, drops, and percent — so the finished mix can be checked against the plan.
- Why does E-Liquid Community calculate in mL?
- Nicotine strength is defined per milliliter (mg/mL), and bases and concentrates are sold by mL, so milliliters avoid rounding drift. All math and saved recipes stay in mL for precision.
- Can I view results in US fl oz or liters?
- Yes. The Display units toggle in the results panel shows volumes in mL, US fl oz, or L. It changes the display only — the underlying math and saved data remain in mL, and the original mL value stays visible for safety.
- What is PG/VG ratio?
- The proportion of propylene glycol to vegetable glycerin in the carrier portion of the mix; added diluent is shown separately. Higher VG is thicker and smoother; higher PG carries flavor more sharply. Every ingredient contributes its own PG or VG, which the calculator accounts for automatically.
- Why can a mix be marked not feasible?
- Some targets can't physically be reached — for example, a 6 mg/mL mix from a 3 mg/mL base, or a max-VG target when the nicotine base and flavors already contribute more PG than the ratio allows. The warning names the failed constraint and suggests what to adjust.
- Should nicotine be handled carefully?
- Yes. Concentrated nicotine is toxic and must be handled with gloves and eye protection, stored securely away from children and pets, and double-checked against independent math before mixing. E-Liquid Community treats nicotine amounts as safety-critical and reminds you to verify them.
- Are recipes saved online?
- No. Saved recipes live in your browser's local storage on your own device — nothing is uploaded. Export JSON for backups. Optional accounts, if ever added, will be deliberate and clearly announced.
- Is this a vape shop?
- No. E-Liquid Community is an adult (21+) informational calculator and recipe notebook. It does not sell nicotine, tobacco, vapor products, or anything else, contains no affiliate links, and makes no health or cessation claims.
