How to use this tool
- Enter the labelled values using the displayed units and explicit assumptions.
- Choose Calculate result and review the complete report and any undefined or no-solution states.
- Choose Download result to save the complete JSON. Reset clears the result and restores example controls.
Examples
Tile length (mm): 300
Tile width (mm): 300
Joint fill depth (mm): 8
Joint width (mm): 3
Tiled area (m²): 20
Grout density (kg/L): 1.6
Extra material (%): 10
Package mass (kg): 5
Limitations
- Positive tile length/width/depth in mm,nonnegative joint width,area m²,density kg/L,waste0–100%,positive package kg. Uses standard approximate (L+W)/(L*W)*depth*joint*density kg/m². No perimeter corrections,product default density,surface roughness or installation guarantee.
- Scalar controls accept explicit finite decimal syntax;positive values normally1e-12–1e12,nonnegative0–1e12 unless a narrower range is stated. JSON numeric rows use finite IEEE754 values within their stated bounds. Derived counts above1billion and nonfinite results refuse. Combined input<=400000UTF8 bytes;complete JSON<=4MiB.
