How many grams are in a cup?
It depends on the ingredient. One cup of water is 240 g, flour is about 125 g, granulated sugar is 200 g, and butter is 227 g. The converter uses ingredient density tables so you can pick "1 cup of flour" and get the correct grams. Volume-to-weight conversions are not interchangeable across ingredients without these density factors.
What is the difference between US and metric tablespoons?
A US tablespoon is 14.79 mL, while a metric tablespoon is 15 mL. An Australian tablespoon is 20 mL, which is significantly larger. UK tablespoons are 17.76 mL but rarely used now; UK recipes typically follow metric. Always check which "tablespoon" a recipe means to avoid over- or under-dosing baking powder, salt, or spices.
How do I convert ounces to grams in a recipe?
Multiply ounces by 28.35 to get grams. So 4 oz of butter is 113 g. Note this is weight, not fluid ounces. US recipes often mix weight (ounces of meat) and volume (cups of flour) on the same page, so read carefully. The converter clarifies both and helps you switch a recipe entirely to metric weights.
Why is baking by weight more accurate?
Volume measurements depend on how packed the ingredient is. A "cup" of flour can range from 110 g (sifted) to 150 g (scooped and packed), a 36 percent variation. Weighing eliminates this entirely, which is why professional bakers and many home recipes now list grams. A kitchen scale with 1 g resolution is the single biggest accuracy upgrade.
How do I convert fluid ounces to millilitres?
Multiply US fluid ounces by 29.5735 or UK fluid ounces by 28.4131 to get millilitres. So 8 fl oz US is 237 mL, and 8 fl oz UK is 227 mL. The roughly 4 percent difference rarely matters for cooking but accumulates across a full recipe. The converter offers both and labels them clearly.
Does the converter handle stick of butter or other US oddities?
Yes. One stick of US butter is 4 oz or 113 g or half a cup or 8 tablespoons. The converter recognises sticks, cups, tablespoons, teaspoons, ounces, and grams for butter and other staples. Common ingredient densities (sugar, flour, rice, milk, oil) are built in so you can switch units mid-recipe with confidence.
