Frequently asked questions
What is the Best Answer Hub Cooking Converter?
The Best Answer Hub Cooking Converter is a free, privacy-first browser tool built for home bakers and cooks. It has two modes: an Ingredient Converter that converts between volume and weight using real ingredient densities — so 1 cup of flour gives a different gram weight than 1 cup of sugar — and a Recipe Scaler that adjusts any recipe up or down and outputs kitchen-friendly fractions like ⅔ and 1 ½ instead of decimals. Everything runs in your browser with no signup and no ads.
How many grams is 1 cup of all-purpose flour?
One US cup of spooned-and-leveled all-purpose flour weighs approximately 125 grams. If you scoop directly from the bag, it can be 140 to 150 grams because the flour gets compacted. Our converter uses 125 grams per US cup as the standard "spooned and leveled" measurement, which is what most professional recipes assume. For UK or metric cups, which are 250 milliliters instead of 236.6, the weight is about 132 grams.
Why does 1 cup of flour weigh less than 1 cup of sugar?
Flour is much less dense than sugar. All-purpose flour has a density of roughly 0.53 grams per milliliter, while granulated sugar is about 0.85 grams per milliliter. This means a cup of sugar weighs around 200 grams, while a cup of flour weighs about 125 grams. The difference matters in baking because using volume measurements for dry ingredients can lead to inconsistent results. Weight is far more reliable.
How do I convert cups to grams for baking?
Select your ingredient in our converter, enter the amount in cups, and choose grams as the output unit. The tool uses the actual density of that specific ingredient — not a generic water conversion — so you get an accurate weight. For example, 2 cups of butter converts to 454 grams because butter is denser than flour. Always use the spoon-and-level method for flour and the packed method for brown sugar to match the densities in our tool.
How many tablespoons are in 1/3 cup?
There are 5 tablespoons and 1 teaspoon in ⅓ cup. Since 1 US cup contains 16 tablespoons, dividing by 3 gives 5.33 tablespoons, which is 5 tablespoons plus 1 teaspoon. Our Recipe Scaler outputs this exact kitchen fraction automatically so you never have to measure awkward decimals like 0.33 cup. For UK measurements, ⅓ of a 250-milliliter cup is about 5.6 UK tablespoons.
What is the difference between a US cup and a UK cup?
A US customary cup holds 236.6 milliliters, while a UK metric cup holds 250 milliliters. This 5.7% difference means that a UK cup of flour weighs about 132 grams, while a US cup weighs about 125 grams. UK tablespoons are also larger — about 18 milliliters compared to 15 milliliters in the US. Our converter includes a US/UK toggle so you can match the cup standard used in your recipe.
How do I scale a recipe from 4 servings to 6?
Use the Recipe Scaler mode in our tool. Enter 4 as the original servings and 6 as the desired servings. Then list each ingredient with its amount and unit. The tool multiplies every ingredient by 1.5 and displays the results in kitchen fractions. For example, 1 cup becomes 1 ½ cups, and 2 tablespoons become 3 tablespoons. You can add or remove ingredient rows as needed.
How many grams is 1 tablespoon of butter?
One US tablespoon of butter weighs approximately 14.2 grams. One stick of butter is 113 grams and equals exactly ½ cup or 8 tablespoons. Our converter handles butter conversions precisely because butter has a fixed density of about 0.96 grams per milliliter. If your recipe calls for tablespoons but you only have a scale, simply select Butter in the converter and switch from tablespoons to grams.
What is the difference between packed and unpacked brown sugar?
Packed brown sugar is pressed firmly into the measuring cup, squeezing out air gaps. This gives a density of about 0.93 grams per milliliter, or 220 grams per US cup. Unpacked or loosely spooned brown sugar has a density of about 0.68 grams per milliliter, or 160 grams per US cup. That is a 37% difference. Our converter offers both options so you can match the method your recipe author intended.
How do I convert baking measurements without a scale?
Use the Ingredient Converter in reverse. Enter the weight in grams and select the volume unit you want — cups, tablespoons, or teaspoons. The tool tells you exactly how much to measure. For example, 250 grams of all-purpose flour equals 2 US cups. Keep in mind that measuring by volume is less accurate than weighing, especially for flour, which can vary by 20% or more depending on how you scoop it.
How many milliliters in a US tablespoon?
One US tablespoon contains exactly 14.787 milliliters. One US teaspoon contains 4.929 milliliters, which means there are exactly 3 teaspoons in 1 tablespoon. In the UK and Australia, a tablespoon is 17.758 milliliters and contains 4 teaspoons of 5.919 milliliters each. This is why a UK tablespoon is roughly 20% larger than a US tablespoon. Our converter handles both standards.
What is a kitchen fraction and why use it?
A kitchen fraction is a common fractional measurement used in recipes, such as ½, ⅓, ¾, or 1 ½ cups. Most measuring cups and spoons are labeled with these fractions, not decimals. Our Recipe Scaler automatically converts scaled amounts like 0.6667 cup into ⅔ cup, or 1.5 cups into 1 ½ cups. This makes it much easier to measure accurately with standard kitchen tools.
How do I halve a recipe that calls for 1 egg?
Half an egg equals about 2 tablespoons or 30 milliliters of beaten egg. The easiest method is to beat the egg in a small bowl, measure out 2 tablespoons, and use that in your halved recipe. You can save the remainder for scrambled eggs or brush it on pastry as an egg wash. Our Recipe Scaler will show "0.5 egg" but we recommend using the beaten-egg tablespoon method for accuracy.
Why do European recipes use weight instead of volume?
Weight is far more precise and repeatable than volume. A cup of flour can vary by 20 to 30 grams depending on humidity, scooping method, and how settled the flour is. A gram scale removes all of that uncertainty. This is why professional bakers and most European home cooks weigh ingredients. Our converter bridges the gap by giving you accurate gram weights for common volume measurements.
How many ounces is 1 cup of shredded cheese?
One US cup of shredded cheese weighs approximately 4 ounces, or 113 grams. The exact weight depends on how finely the cheese is shredded and how tightly it is packed into the cup. Coarsely shredded cheddar is about 100 grams per cup, while finely shredded parmesan can be 120 grams per cup. For the most consistent results in cooking, weighing cheese on a scale is recommended.
Real-world conversions
Two US cups of spooned-and-leveled all-purpose flour equals 250 grams. If you scoop straight from the bag, the same 2 cups can weigh 280 to 300 grams. This 50-gram difference is enough to make a cake dry or dense.
A recipe that makes 24 cookies can be scaled to 36 by multiplying every ingredient by 1.5. One cup becomes 1 ½ cups, and 2 tablespoons become 3 tablespoons. Our Recipe Scaler outputs these kitchen fractions automatically.
A UK metric cup is 250 milliliters, while a US cup is 236.6 milliliters. For all-purpose flour, that means a UK cup weighs about 132 grams versus 125 grams in the US. Our system toggle prevents this 5.6% error that can ruin baked goods.
Honey is 43% denser than water, so a quarter cup weighs 85 grams rather than the 59 grams you might expect. Using a scale for honey is far more accurate than trying to level it in a measuring cup. Our converter knows honey's exact density.
Densities are based on standard cooking references. Actual weights vary by brand, humidity, and measuring technique. For best results, use a digital kitchen scale.
