How the cooking converter works
Volume units in US recipes are linked by simple ratios, and the calculator converts everything through milliliters.
1 tbsp = 3 tsp = 14.79 mL
Grams = cups × grams per cup for the ingredient
Converting volume to weight depends on density, so a cup of flour weighs far less than a cup of honey. The gram values used are typical figures from baking references: all-purpose flour 120 g per cup (spooned and levelled), granulated sugar 200 g, packed brown sugar 220 g and butter 227 g (two sticks). UK and Australian cups are 250 mL, slightly larger than the US cup.
Worked example
A recipe calls for 1 cup of flour. That is 120 g, 236.59 mL or 16 tablespoons. Half a cup of butter is one stick, about 113.5 g. Three tablespoons of honey is 0.1875 cup, or about 64 g.
Frequently asked questions
How many grams is a cup of flour?
About 120 g for all-purpose flour spooned into the cup and levelled; scooping directly can give 140 g or more.
How many tablespoons are in a cup?
16.
How many mL is a US cup?
236.59 mL. Recipes often round it to 240 mL.
Is a fluid ounce the same as an ounce of weight?
Only for water, approximately. A fluid ounce measures volume; an ounce measures weight.
