The resin calculator helps artists, craftspeople, and industrial users calculate the exact amount of epoxy resin and hardener needed for any project. Whether you’re looking for a resin calculator in cm for mold volume, resin calculator in ml for precise mixing, resin calculator in grams for weight-based mixing, a resin calculator 2:1 ratio tool for standard epoxy systems, or a free epoxy resin calculator for tabletops and countertops — this tool covers everything. Also popular as a resin calculator app free download alternative that works directly in your browser. Note: If you searched for resin calculator Genshin, that refers to the in-game Resin system in Genshin Impact — we’ve included a section for that too!
Select “Mold/Shape” to calculate resin by mold dimensions, “By Volume (ml)” if you already know the total volume needed, or “Genshin Resin” for the game’s resin tracking system.
For mold mode: select shape (rectangle, cylinder, sphere, cone), enter dimensions in cm, mm, or inches, and set fill percentage. For volume mode: directly enter the total ml needed.
Choose your resin system ratio — 2:1 is most common for epoxy, 1:1 for casting resins, 3:1 or 4:1 for specialized systems. Add wastage factor (10% recommended) to avoid running short.
Instantly see total mixed volume in ml, resin part in ml, hardener part in ml, and total weight in grams — ready to measure out for mixing. Never waste expensive resin again.
2:1 Ratio (most common): Resin = Total × 2/3 | Hardener = Total × 1/3
1:1 Ratio: Resin = Total / 2 | Hardener = Total / 2
Volume from mold (rectangle): Volume = L × W × H (in cm³ = ml)
Cylinder: Volume = π × r² × H | Sphere: Volume = (4/3) × π × r³
Weight in grams: Grams = Volume (ml) × Density (g/ml)
Standard epoxy density: 1.0–1.2 g/ml
Rectangle, Cylinder, Sphere, and Cone — all with correct volume formulas. Works as a resin calculator in cm, mm, or inches. Perfect for tabletops, coasters, jewelry molds, and industrial castings.
A bonus mode for Genshin Impact players — track resin regeneration time, plan domain runs, and never miss your resin cap again. Works for both 160 and 200 resin cap systems.
Shows results in ml AND grams simultaneously with automatic ratio splitting — eliminating the need to separately calculate resin and hardener portions. Supports 2:1, 1:1, 3:1, 4:1, and custom ratios.
Whether you need a resin calculator in ml for art projects, a resin calculator in grams for industrial mixing, an epoxy resin calculator for tabletops, a resin calculator 2:1 ratio tool, or even a Genshin Resin tracker — this free all-in-one calculator has you covered. Calculate first, mix second, and never run short or waste expensive epoxy resin again.
