• Bottle math for vape shops comes down to two numbers: the target nicotine strength in milligrams per milliliter (mg/ml) and the total volume you're mixing. Multiply them to get the total nicotine needed, then subtract what your nicotine base already provides. The Windbar E-liquid Calculator automates this process, reducing errors when you're scaling recipes for retail.
• Bottle math is just multiplication and subtraction—no advanced chemistry needed.
• Always double-check your nicotine base strength before mixing; a mistake here throws off the whole batch.
• Use the Windbar E-liquid Calculator for quick, accurate results every time.
• Keep a simple formula sheet by your mixing station for spot checks.
