How it works
- T = A × ( + ) / ; T = B × ( + ) /
- Resin amount = × / ( + ); Hardener amount = × / ( + )
- Worked example: 300 g, 2:1 ⇒ 200 g + 100 g; 300 mL, 3:1 ⇒ 225 mL + 75 mL

Assumptions and limitations
Start from total mixture, resin or hardener amount. Enter total mixed quantity in grams for weight ratios or mL for volume ratios. Ratio parts must both be positive and match the manufacturer’s specified basis. A weight ratio cannot be reused as a volume ratio without reviewed component densities; changing basis does not convert your numbers. Volume amounts are ingredient measuring volumes, not a guaranteed cured yield. No density, temperature, cure-time, shrinkage or product-specific adjustment is inferred.
