Volume ⇄ weight uses each ingredient’s typical density, so results are approximate. Spoons and cups are US measures.
About this tool
This cooking converter changes ingredient amounts between cups, grams, milliliters, tablespoons, teaspoons and ounces, so you can follow any recipe no matter which system it uses. Because a cup of flour and a cup of sugar weigh very different amounts, you can pick the ingredient and the tool uses its density for an accurate cup-to-gram result. It is handy for cooks working from recipes written abroad or switching between volume and weight. Everything runs in your browser, so your entries stay on your own device and work even offline once the page has loaded.
Frequently asked questions
Why does a cup of flour weigh less than a cup of sugar?
Because they have different densities. A cup measures volume, but the same volume holds different weights depending on how heavy and how tightly packed the ingredient is. One US cup of all-purpose flour is only about 120 g, while a cup of granulated sugar is around 200 g, a cup of butter about 227 g and a cup of water roughly 237 g. That is why the tool asks which ingredient you are measuring before it converts cups to grams.
Should I weigh ingredients instead of using cups?
For baking, weighing with a kitchen scale is far more reliable. A cup of flour can vary by 20 percent or more depending on whether it is scooped or spooned and how settled it is, and that swing can ruin a delicate cake or loaf. Grams remove the guesswork. For soups, stews and everyday cooking, volume measures are usually accurate enough, so cups and spoons are perfectly fine.
Is my recipe data sent to a server?
No. Every conversion is calculated by JavaScript running directly in your browser, so the ingredients and amounts you enter are never uploaded to or stored on any server. Once the page has loaded you can even use it offline, with no account and no tracking, and nothing you type ever leaves your own device.
