The Epoxy Resin Volume Calculator determines total liquid epoxy requirements in fluid ounces and milliliters based on pour surface dimensions, mold depth, and resin mix ratios.

### Geometric Volume & Mixing Formulas Resin volume calculations convert cubic dimensional capacity into liquid volumetric units while incorporating standard mixing container waste: - **Cubic Volume Capacity**: $$\text{Cubic Volume (cu in)} = \text{Length (in)} \times \text{Width (in)} \times \text{Depth (in)}$$ - **Total Fluid Ounces with 5% Waste Allowance**: $$\text{Total Volume (fl oz)} = \text{Cubic Volume} \times 0.554113 \times 1.05$$ - **Metric Conversion**: $$\text{Total Volume (ml)} = \text{Total Volume (fl oz)} \times 29.5735$$ - **Mix Ratio Apportionment**: - **1:1 Equal Volume Ratio**: Part A (Resin) = $\text{Total} / 2$; Part B (Hardener) = $\text{Total} / 2$ - **2:1 Deep Pour Ratio**: Part A (Resin) = $(\text{Total} \times 2) / 3$; Part B (Hardener) = $\text{Total} / 3$

### Worked Calculation Example Pouring an epoxy river table void measuring 36.0 inches long, 12.0 inches wide, and 1.0 inch deep using a 1:1 mix resin: - **Cubic Inches**: $36.0 \times 12.0 \times 1.0 = 432.00\text{ cu in}$ - **Liquid Fluid Ounces**: $432.00 \times 0.554113 \times 1.05 = 251.35\text{ fl oz}$ - **Metric Total**: $251.35 \times 29.5735 = 7{,}433\text{ ml} \quad (\approx 7.43\text{ Liters})$ - **Part A (Resin)**: $251.35 / 2 = 125.68\text{ fl oz}$ - **Part B (Hardener)**: $251.35 / 2 = 125.68\text{ fl oz}$
