Example

Input: Butter: 1 stick

Result: 0.50 cups, 8.0 tablespoons, 113.4 grams, 4.00 ounces

A US stick of butter is a quarter pound (4 oz); 4 x 28.35 g = 113.4 g, which is 8 tablespoons or half a cup.

Celsius rounded to the nearest degree, as the calculator shows it.

  1. Select a tab - butter, egg sizes, oven temperature, or pan sizes.
  2. For butter, enter the amount in sticks, cups, tablespoons, grams, or ounces to see all equivalents.
  3. For eggs, enter the number of eggs and the egg size your recipe calls for to see the equivalent count in every other size.
  4. For oven temperatures, enter a value in Fahrenheit, Celsius, or Gas Mark to convert between all three.
  5. Copy the conversion results you need directly into your recipe notes.

Butter, Eggs, Oven Temperatures and Pan Sizes

This baking calculator handles four conversions that recipes from other countries often need. A US stick of butter is 1/2 cup, 8 tablespoons, 113.4 g or 4 oz. 350 F is 177 C, about Gas Mark 4. It also swaps egg sizes and compares baking pans.

The Butter tab takes an amount in sticks, cups, tablespoons, grams or ounces and shows all the others. US butter often comes in quarter-pound sticks with tablespoon marks on the wrapper. European butter is sold by weight, often in 250 g blocks, which is about 2.2 sticks.

The Egg Sizes tab helps when you have a different size than the recipe asks for. It uses weights of 42 g for small, 49 g for medium, 56 g for large, 63 g for extra large and 70 g for jumbo. Three large eggs weigh 168 g, the same as 4 small eggs or 2.4 jumbo eggs. Most recipes assume large eggs. For a fraction of an egg, beat it and use part.

The Oven Temp tab converts Fahrenheit, Celsius and Gas Mark, the scale used on many older British gas ovens. Each Gas Mark step from 1 to 10 is 25 F, from 275 F at Gas Mark 1 to 500 F at Gas Mark 10. Values between steps are blended.

The Pan Sizes tab compares round, square and 9 x 13 in pans by area. A 9 in round pan holds about 27% more than an 8 in round, so batter sits thinner and bakes faster. For cups to grams by ingredient, use the Cooking Measurement Converter. For other temperatures, see the Temperature Converter.

Frequently Asked Questions

A US stick of butter is 113.4 g, or 4 oz. That equals 8 tablespoons or 1/2 cup. So 2 sticks are 1 cup (226.8 g), and 4 sticks are 1 pound (453.6 g). A 250 g European block is about 2.2 sticks.
350 F is 176.7 C, usually rounded to 175 or 180 C on oven dials, and it is Gas Mark 4. Other common settings are 325 F (163 C, Gas Mark 3), 375 F (191 C, Gas Mark 5) and 400 F (204 C, Gas Mark 6).
Many bakers lower the temperature by about 20 C, or 25 F, for a fan (convection) oven, because moving air cooks faster. Some recipes already give fan temperatures, so check first. This tool converts the number you enter and does not adjust for fan ovens.
Yes, if you adjust the count. The tool uses 56 g for a large egg and 49 g for a medium one. Three large eggs (168 g) match about 3.4 medium eggs, so use 3 medium eggs plus a little extra beaten egg. For one or two eggs, the swap rarely matters.
Yes. A 9 in round pan has about 27% more area, so the batter will be thinner. Start checking a few minutes early. Going from a 9 x 13 pan to two 8 in rounds also works well, since their areas are close: 117 sq in against about 100.
