How to Convert Grams to Cups and Tablespoons

Updated 6 November 2026 · Standard formula, shown below

This guide shows you how to convert a weight in grams to volume in cups and tablespoons for everyday cooking and baking. You enter the number of grams and the ingredient, and you get the equivalent in US cups and tablespoons, based on the ingredient’s density. No special tools are needed beyond a calculator or the conversion steps below.

What You’ll Need

A kitchen scale (to weigh the ingredient if you don’t already have grams)
A calculator or pen and paper
The density of your ingredient (provided in the tables below for common items)

Step-by-Step

Identify the ingredient. Different ingredients have different densities. For example, 100 grams of flour is not the same volume as 100 grams of sugar. Check the ingredient list on your recipe or package.
Find the density. Use the table below to find the grams per cup (g/cup) for your ingredient. If it’s not listed, look up the density online (e.g., “density of almond flour g per cup”) or use a general conversion factor if you know it.
Convert grams to cups. Divide the number of grams by the grams per cup for your ingredient. The result is the number of cups. For example, 200 grams of all-purpose flour (120 g/cup) is 200 ÷ 120 = 1.67 cups.
Convert cups to tablespoons. If you need tablespoons instead of cups, remember that 1 US cup = 16 tablespoons. So multiply the number of cups by 16. From the example, 1.67 cups × 16 = 26.7 tablespoons.
Adjust for metric cups (if needed). If you are using a metric cup (250 ml) instead of a US cup (240 ml), the conversion factor changes. For metric cups, 1 cup = 250 ml, so grams per metric cup = density (g/ml) × 250. Use that in your calculation.

Common Mistakes

Using the same conversion for all ingredients. This is the biggest error. Sugar and flour have very different densities, so 1 cup of each weighs differently.
Confusing US and metric cups. The US cup is 240 ml, while the metric cup is 250 ml. This 4% difference can affect baking results.
Rounding too early. If you round 1.67 cups to 2 cups, you’ll add too much flour. Keep at least two decimal places until the final step.
Ignoring the ingredient’s state. For example, grated cheese vs. cubed cheese have different densities. Always use the density for the form you have.

Tips

Use a kitchen scale for best accuracy. Volume measurements are less precise than weight, especially for dry ingredients. If you can, weigh your ingredients.
Spoon and level flour. When measuring flour by volume, spoon it into the cup and level off with a knife. Don’t pack it down.
Use the tables for common ingredients. Here are approximate grams per US cup (240 ml) for common ingredients:
- All-purpose flour: 120 g
- Granulated sugar: 200 g
- Brown sugar (packed): 220 g
- Butter: 227 g (1 cup = 2 sticks)
- Milk: 240 g (density 1 g/ml)
- Water: 240 g
- Honey: 340 g
- Rolled oats: 80 g
For liquids, use the density of water. Most liquids like milk, water, and juice have a density close to 1 g/ml, so 1 cup (240 ml) ≈ 240 g.

Troubleshooting

My result seems off. Double-check the density you used. If you used a generic online converter, it might have used a different density. For example, some sources list flour at 125 g/cup instead of 120 g/cup. That’s a 4% difference, which can matter in baking.

I don’t have the ingredient in the table. Look up the density in grams per milliliter (g/ml) from a reliable source, then multiply by 240 to get grams per US cup. For example, if the density is 0.9 g/ml, then 0.9 × 240 = 216 g/cup.

My recipe uses metric cups. If you are in a country that uses metric cups (250 ml), adjust the conversion. Use 250 ml instead of 240 ml in the calculation. For water, 1 metric cup = 250 g.

I’m converting a recipe that calls for grams but I only have cups. You can use the reverse: take the grams and divide by the grams per cup to get cups. Then use the cups to measure. That’s exactly what this guide does.

Frequently Asked Questions

How many grams are in a cup? It depends on the ingredient. A cup of water weighs 240 grams, but a cup of flour weighs about 120 grams. Always check the specific ingredient.

How many tablespoons are in a cup? There are 16 tablespoons in 1 US cup. So to convert cups to tablespoons, multiply by 16.

Can I convert grams to cups for any ingredient? Yes, if you know the density (grams per cup) of that ingredient. The conversion is straightforward: grams ÷ grams per cup = cups.

Is it better to measure by weight or volume? For baking, weight is more accurate and consistent. Volume measurements can vary due to how you scoop, pack, or sift the ingredient.

What is the difference between a US cup and a metric cup? A US cup is 240 ml, while a metric cup is 250 ml. That’s about a 4% difference, which can affect recipes.

How do I convert grams to tablespoons directly? First convert grams to cups (divide by grams per cup), then multiply by 16 to get tablespoons. Or, if you know the grams per tablespoon (which is grams per cup divided by 16), divide grams by that number.
