About Pantry Math

Pantry Math is a small collection of free kitchen calculators for the questions that come up halfway through a recipe: how many grams is a cup of flour, how do I make this for six instead of four, how much water goes into a 75% hydration dough.

Every tool runs right in your browser. There is nothing to install, no account to create, and nothing you type is sent to us.

How the numbers are made

Ingredient weights use the standard US cup (236.6 ml) and published reference weights for spooned-and-levelled ingredients. Oven, pan and ratio conversions use standard formulas. Real ingredients vary by brand, humidity and how you measure, so treat results as a reliable starting point and trust your eyes and taste.
