What these calculators are for
FoodMachHub is a set of free calculators for bakers, brewers, cooks, caterers and small food businesses. Each page answers one practical question with numbers you can check: what a dish or a recipe costs and what to charge, how to scale a recipe or a dough, how much starter, water and salt a sourdough needs, how strong a beer or wine is, how much salt and curing salt a brine needs, how long a product keeps at a lower temperature, and what a Nutrition Facts or Supplement Facts panel looks like for your values.
Every calculator works the same way:
- Shows the working. Under each result is the formula filled in with your numbers.
- Metric or US units. Grams or ounces, milliliters or fluid ounces, °C or °F — each value has its own unit menu.
- Print or save. “Print / save as PDF” gives a sheet with your inputs, results, the calculation steps and the date; the label generators also download the label as SVG or PNG.
- Share a link. The page address holds your inputs, so a copied link opens the same calculation.
- Private. Everything is calculated in your browser. Nothing you type is uploaded, and there is no account.
The results are calculated from the values you enter. Nutrient values, food-safety limits and shelf life must come from your own data, tests and the rules that apply to you. You may use the results and the labels in commercial work, including product packaging, menus and costing sheets.
