How To Use

Step-by-Step: Epoxy Resin Calculator

Choose Your Mode

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.

Enter Dimensions or Volume

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.

Select Mix Ratio

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.

Get Resin & Hardener Amounts

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.

Formula

Resin Calculator Formula Explained

Resin Part = Total Volume × Ratio ÷ (Ratio + 1)

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

Smart Features

Why This Resin Calculator Stands Out

4 Shape Modes

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.

Genshin Resin Tracker

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.

ml, grams & Ratio Together

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.

FAQ

Resin Calculator — People Also Ask

What is resin calculator 2:1 and how does it work?

A 2:1 ratio means 2 parts resin to 1 part hardener by volume. So for 300ml total: Resin = 200ml (2/3 of total), Hardener = 100ml (1/3 of total). This is the most common ratio for epoxy resin systems used in tabletops, countertops, and art resin. Always check your specific resin brand’s datasheet — some use weight ratio (by grams) instead of volume ratio.

How to calculate resin in ml for a mold?

Calculate mold volume in cm³ — which equals ml directly. For a rectangular mold: Volume (ml) = Length × Width × Depth (all in cm). For a 20cm × 10cm × 2cm mold: 20×10×2 = 400 ml total. Then apply your ratio: for 2:1, you need 267ml resin + 133ml hardener. Always add 10–15% extra for spills and overflow.

How to use resin calculator in grams vs ml?

Some resin systems specify ratio by weight (grams), others by volume (ml). 1 ml of epoxy resin weighs approximately 1.0–1.2 grams depending on the formulation. Our calculator converts ml to grams automatically using your input density. If your resin brand specifies 2:1 by weight: weigh 200g resin + 100g hardener for 300g total. Always follow your specific brand’s instructions.

What is Genshin Impact resin calculator?

Genshin Impact uses “Original Resin” as the stamina system for claiming rewards from Domains, Bosses, and Ley Lines. Resin regenerates at 1 per 8 minutes (max 160 or 200 with expansion). Domain runs cost 20 resin, Boss fights cost 40 resin. Use our Genshin Resin tab to calculate regeneration time and plan your daily farming efficiently without wasting resin at cap.
