Cooking Measurement Conversion Guide ()

Cooking measurements are one of the most searched conversion topics online — and for good reason. US recipes use cups and tablespoons, while the rest of the world uses grams and milliliters. Even within the US, baking by weight is more accurate than by volume because the same cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped. Professional bakers always weigh ingredients.

Why Volume-to-Weight Conversions Aren't Simple

A cup of water weighs 236g. A cup of all-purpose flour weighs about 125g. A cup of honey weighs 340g. Volume measures space; weight measures mass — and different ingredients have different densities. This is why our ingredient selector matters: converting "1 cup" to grams gives a completely different answer for flour versus sugar versus butter. Our converter uses the same gram-per-cup values used by professional recipe developers and the USDA.

US vs UK vs Metric Measurements

The US and UK use slightly different measurement systems that cause confusion in international recipes. A US cup is 236.6ml, while a UK/Australian/Canadian cup is typically 250ml — a 5% difference that matters in baking. Tablespoons are slightly different too: a US tablespoon is 14.79ml while a UK tablespoon is 15ml. For most cooking this difference is negligible, but for baking where precision matters, always check which system a recipe uses.

Ingredient	1 Cup (grams)	1 Tbsp (grams)	1 tsp (grams)

How many tablespoons are in a cup?

There are 16 tablespoons in 1 US cup. This is one of the most useful kitchen conversions to memorize: 1 cup = 16 tbsp, ¾ cup = 12 tbsp, ½ cup = 8 tbsp, ¼ cup = 4 tbsp. There are also 3 teaspoons in 1 tablespoon, making 1 cup equal to 48 teaspoons.

How many ml in a cup?

One US cup equals 236.588ml (typically rounded to 240ml for everyday cooking). The UK, Australian, and Canadian cup is 250ml. For baking precision, use the exact value of 236.6ml. For cooking where precision is less critical, 240ml is a practical approximation that's within 1.5% of the true value.

How many grams in a cup of flour?

One cup of all-purpose flour weighs approximately 125 grams when spooned into the measuring cup and leveled — this is the standard method used by most American recipe developers. If you scoop flour directly with the cup (packing it), you can get up to 160 grams, which is 28% more than intended. This is why professional bakers always weigh flour. Bread flour is slightly heavier at about 130g per cup; cake flour is lighter at about 114g per cup.

How many cups is 250ml?

250ml equals approximately 1.057 US cups — just barely more than 1 cup. For practical purposes, 250ml is often treated as equivalent to 1 cup in recipes, though technically it's slightly more. If a recipe calls for 250ml and you're using US cup measures, 1 cup (236ml) plus 1 tablespoon (15ml) = 251ml is the most accurate measurement.

How do I convert a recipe from cups to grams?

The most accurate way to convert cups to grams is to use ingredient-specific conversion factors, since different ingredients have different densities. Use the Ingredient tab above to convert each ingredient individually. As a rough guide: flour = 125g per cup, sugar = 200g per cup, butter = 227g per cup, liquids = 240g per cup. For best baking results, invest in a digital kitchen scale — weighing ingredients is faster, more accurate, and produces more consistent results than volume measuring.

What is a stick of butter in cups?

One stick of US butter equals ½ cup, 8 tablespoons, 4 fluid ounces, or 113 grams. US butter is sold in 4-stick packages (1 pound / 454g total), with each stick wrapped and pre-marked with tablespoon measurements. European butter is often sold in 250g blocks without sticks — one US stick is approximately half a European 250g block.
