Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Use the manufacturer’s mass ratio and mixed density. A volume ratio must not be entered as a mass ratio.
Example Calculation
- Area: 10 m²
- Thickness: 1 mm
- Mixed density: 1.1 kg/L
- Resin-to-hardener mass ratio: 2
- Waste allowance: 10 %
10 m² at 1 mm with 10% waste and density 1.1 kg/L needs 12.1 kg mixed material.
Frequently asked questions
How do I use this calculator?
Enter area, thickness, mixed density, resin-to-hardener mass ratio, waste allowance. The result updates automatically. Use Reset to restore the example values.
What method does it use?
liters=area × thickness × (1+waste); mass=liters × density; resin=mass × ratio/(1+ratio).. Use the manufacturer’s mass ratio and mixed density. A volume ratio must not be entered as a mass ratio.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
