15 free food, cooking and cost calculators
Free tools, no account required, with every calculation running entirely in your browser: nutrition, bread baking, pastry, costs and management. Each calculator has its own page, documented formulas and clearly stated limits.
How these tools are designed
The math is explicit, constants are sourced (NIST, Dietary Reference Intakes, versioned professional conventions) and results are deterministic: same inputs, same outputs. Uncertain estimates are flagged as conventions rather than presented as standards. Nothing you type leaves your browser, no account is required, and no page needs JavaScript to read the method or the FAQ.
