How to Use the Recipe Measurement Converter

Select your ingredient from the search box, then type a value in any field. All other measurements update instantly based on the ingredient’s density. Toggle between US, UK, and Metric units with the region selector. Use the recipe list to save multiple ingredient conversions and copy the full list to your clipboard.

About This Tool

A density-based recipe measurement converter for 65+ common cooking and baking ingredients. Unlike simple volume converters, this tool accounts for the fact that a cup of flour (125 g) weighs much less than a cup of honey (340 g). Every conversion uses the ingredient’s specific density to translate between cups, tablespoons, teaspoons, milliliters, fluid ounces, grams, and ounces. The region selector adjusts cup sizes for US (236.6 ml), UK (284.1 ml), and Metric (250 ml) standards. Pair with the Temperature Converter for oven temperature conversions and the Weight Converter for non-food weight measurements.

Frequently Asked Questions

Why do cups-to-grams conversions differ by ingredient?

A cup is a volume measurement (236.6 ml in the US), but grams measure weight. Different ingredients have different densities — a cup of flour weighs about 125 g, while a cup of honey weighs about 340 g. This tool uses per-ingredient density data to give accurate conversions.

What is the difference between US, UK, and Metric cups?

A US cup is 236.588 ml, a UK (Imperial) cup is 284.131 ml, and a Metric cup (used in Australia and NZ) is 250 ml. Tablespoons also differ: US = 14.787 ml, UK = 17.758 ml, Metric = 20 ml. This tool adjusts all volume conversions based on your selected region.

How accurate are these conversions?

The density values are sourced from USDA food composition data and are accurate for typical kitchen conditions. Real-world variation (how tightly you pack flour, humidity, brand differences) means results are accurate to within about 5%, which is more than sufficient for cooking and baking.

Do I need to register to use the Recipe Measurement Converter?

No. The Recipe Measurement Converter works fully without an account, and all conversions between cups, grams, tablespoons, teaspoons, and milliliters for 65+ ingredients happen in your browser. Your recipe list is saved locally in your browser’s localStorage for convenience across sessions, but nothing is ever transmitted to a server.
