How this works
Butter has a density of about 0.959 g/mL (standard: 1 cup = 227g). That means 1 mL of butter weighs 0.959 grams.
Teaspoons = grams × 0.2116
Note: Salted or unsalted; same density. 1 stick = 1/2 cup = 113g.
Why a cup of butter doesn't always weigh the same
Volume measurements are forgiving in some ways and brutal in others. A cup of butter can vary by 10-20% in weight depending on how it's measured: spooned vs scooped, packed vs loose, sifted vs unsifted. The density figure used here (0.959 g/mL) matches the most common published recipe conventions, but if you're after baking precision, weighing on a kitchen scale is more accurate than measuring by volume.

Volume vs weight in cooking
The American convention of measuring ingredients by volume (cups, tablespoons, teaspoons) is convenient but introduces variability that doesn't exist in weight-based recipes. Most professional bakers and bakeries weigh ingredients to within a gram because the structure of baked goods depends on precise ingredient ratios. For everyday cooking — soups, sauces, sautés — the volume-to-weight imprecision rarely matters. For baking that depends on rising or texture (cakes, breads, laminated doughs), it matters a lot.
The conversion
Multiplying the volume of butter by its density (0.959 g/mL) gives the weight in grams. The calculator at the top of this page does the math automatically; the formula box above shows the resulting linear factor for the specific volume and weight units selected here.
