Butter: Cups to Grams

Butter is one of the easier ingredients to convert because it's sold in standard blocks. One cup of butter weighs about 227 grams, which equals two US sticks. That means 1 stick is half a cup or roughly 113g, half a stick is a quarter cup or about 57g, and a single tablespoon of butter is around 14g. These figures work for both salted and unsalted butter since the small amount of salt doesn't meaningfully change the weight.

This converter is a lifesaver when a US recipe lists butter in cups or sticks and your butter comes in a 250g block with no stick markings. Enter the cup amount and you'll get grams to weigh straight off the wrapper. A practical tip: many butter wrappers print tablespoon and gram lines along the side, so you can often slice off the exact amount with a knife and skip melting or packing it into a measuring cup altogether.

How to convert between cups, grams and ounces accurately

The reason a single “cup to grams” number never works is that a cup measures volume while grams measure weight. A cup of feathery flour holds far less mass than a cup of dense honey, so the only accurate way to convert between volume and weight is to use each ingredient’s density. This converter stores tested densities for dozens of common cooking and baking ingredients, so you get the right number every time.

Volume-to-volume (cups → tablespoons) and weight-to-weight (ounces → grams) conversions are fixed ratios and don’t depend on the ingredient. You only need to pick an ingredient when you cross between the two, for example cups to grams, or ounces to cups.

Common cup-to-gram weights

Weights are spooned-and-levelled and based on commonly referenced King Arthur Baking and USDA densities. For the most reliable baking, weigh ingredients with a digital scale.
