Convert butter between full or half-size US sticks, cups, spoons, grams, ounces, and pounds. The result includes all equivalents, so you can compare a recipe with the markings on your package.
Read the package first
Enter the amount and choose the measure you have, then select the destination. If the package uses half-size sticks, choose that option rather than Full US sticks. A recipe multiplier can double or halve the amount without changing the unit relationship.
Outside the United States, butter is often sold in blocks of a stated weight. Enter the actual grams or ounces instead of assuming the block counts as one stick. This tool does not infer a regional block size.
US package reference
| Amount | US cups | US tablespoons | Weight |
|---|---|---|---|
| Half a full stick | 1/4 | 4 | 2 oz |
| One full stick | 1/2 | 8 | 4 oz |
| Two full sticks | 1 | 16 | 8 oz |
| Four full sticks | 2 | 32 | 1 lb |
These are package conventions for butter, not a rule that any cup of food weighs eight ounces. The spoon option is US tablespoons, not a 20 mL Australian tablespoon.
Examples
One and a half full sticks
1 1/2 full sticks = 3/4 US cup = 12 US tablespoons, or approximately 170.0971 g. The gram output follows the ounce definition rather than rounding each stick before multiplying.
A recipe using half-size sticks
Two half-size US sticks equal one full stick, or 1/2 US cup. Four half-size sticks equal one US cup, not two cups.
Formula
1 pound = 453.59237 grams
1 full US stick = 1/4 pound = 113.3980925 grams
1 US cup of butter = 2 full sticks
1 US tablespoon of butter = 1/8 of a full stick
The recipe multiplier applies to the entered amount before all equivalents are calculated.
Rounding and ingredient state
The exact conversion factor does not mean a cut piece of butter can be measured to many decimal places. Wrappers round their gram equivalents and cutting introduces practical variation. A whipped spread, margarine, or another substitute may not have the same volume-to-weight relationship as standard butter.

Land O’Lakes’ butter FAQ describes full and half-stick cup and tablespoon equivalents. If your product supplies a different weight or measure, follow its labeling. Use the general Cooking Measurement Converter for explicitly selected metric volumes or a custom density.
