Sandustry Production Ratio Scaler
Why manual? Early Access ratios can change and some community ratios are approximate. This tool does not invent or hard-code a recipe: enter the ratio you have verified, then scale it.
Evidence: Manual browser scaler — no hard-coded recipe database

Primary source
Enter a verified ratio and target output.
Example
If a verified recipe says 2 input produces 3 output, and you want 30 output, enter 2 / 3 / 30. The tool returns 20 input. The math is generic; the game ratio remains your responsibility to verify.
Evidence boundary
The calculator is a generic shell, not a Sandustry recipe reference. Ratios stay user-entered so the site never publishes unverified production math as if it were official data.
