## Convert & Scale Any Recipe


### Pick an ingredient

Choose an ingredient, enter an amount, and select a unit. The tool converts to cups, grams, ml, oz, tbsp, tsp based on real ingredient density.


### No recipe yet

Paste a recipe on the left or click a sample chip. Each line is auto-parsed for quantity, unit, and ingredient name.


## How This Recipe Converter Works

The recipe converter uses a curated density table of 80+ common baking and cooking ingredients based on USDA FoodData Central. Every conversion from volume (cups, tablespoons, teaspoons) to weight (grams, ounces) or vice versa uses the actual density of the ingredient — not a generic ratio. 1 cup of flour weighs 120 g, 1 cup of honey weighs 340 g, 1 cup of butter weighs 227 g, 1 cup of rice weighs 185 g. Generic unit converters (and AI assistants) get these wrong constantly.


## Problem Solver, Not Feature Provider

A bare unit converter converts 1 cup to 240 ml — correct for water but wrong for flour. Generic AI chatbots are notoriously bad at recipe conversions: ask ChatGPT or Claude how many grams are in a cup of all-purpose flour and you'll see 100 g, 125 g, 140 g, or 150 g, all wrong. They cannot auto-parse an arbitrary recipe line ("2 cups sifted cake flour") and apply the right density. They cannot round 1.33 eggs into 1 egg plus 1 yolk. They cannot enforce baking precision for salt and yeast but cooking looseness for vegetables.

This tool solves the everyday problem every home cook faces: scaling a recipe up or down, converting between metric and US, and using a kitchen scale instead of measuring cups. The deterministic density table, parser, and rounding rules are reproducible and auditable — no hallucination.


## Frequently Asked Questions

**How accurate is this converter?**

Conversions use 80+ ingredient densities from USDA FoodData Central. For most baking and cooking applications, results match published tables (King Arthur, Serious Eats, Sally's Baking) within 2–5 grams per cup. For ultra-precise lab or commercial baking, weigh your flour with a calibrated scale.

**Does the recipe parser handle fractions and ranges?**

Yes. The parser accepts whole numbers (2), decimals (1.5), fractions (1/2, 1/4, 3/4), mixed numbers (1 1/2), and ranges (2–3). It handles units in singular and plural: 1 cup / 2 cups / 1 tbsp / 2 tablespoons. For ranges it uses the midpoint.

**Can I convert metric recipes to US and vice versa?**

Yes. Paste a recipe in grams or ml, set output to US, and the tool converts grams to cups using the ingredient density (e.g. 250 g flour becomes 2 cups + 2 tbsp). Paste US cups, set output to metric, and it converts to grams (1 cup flour = 120 g).

**How does the egg rounding work?**

When a recipe scales to a non-integer number of eggs (e.g. 1.33), the tool rounds to the nearest whole egg (1) and notes the difference (0.33 egg = use 1 yolk or beat 1 egg and use 1/3 of it). This is how professional bakers handle it.

**Why does baking mode round differently?**

Baking is chemistry. Salt, yeast, baking soda/powder, and spices are measured in small amounts where fractions matter. Baking mode rounds to the nearest gram (or 1/8 tsp for spices) instead of friendly fractions. Cooking is forgiving — cooking mode rounds to 1/4, 1/3, 1/2 cup or tsp because you can taste and adjust.

**Can I print or save the scaled recipe?**

Yes. Click "Copy Recipe" to copy the scaled recipe as plain text to your clipboard. Click "Print" to open your browser's print dialog with a clean recipe-only layout (no input form, no extra sections).

**Does it work on mobile?**

Yes. The interface is touch-friendly and the panels stack vertically on narrow screens.

**Is my recipe data private?**

100% private. Everything runs in your browser. Nothing is uploaded, nothing is stored on a server. Close the tab and your recipe is gone.

**What if my ingredient isn't in the list?**

The parser falls back to a generic water-density conversion for unknown ingredients (1 cup = 240 ml = 240 g) and marks the line as "generic density" so you know to substitute the actual value. The single-ingredient converter has 80+ common ingredients pre-loaded.
