In short
One gram of cornflour / cornstarch is 0.1333333333 tablespoon. Going the other way, one tablespoon is 7.5 gram. That works out at 2 gram = 0.2666666667 tablespoon and 4 = 0.5333333333. The figure comes from cornflour / cornstarch weighing 120 g per US cup — a generic cups-to-grams converter assumes water and will give you the wrong answer here, because volume to weight depends entirely on what is in the cup.

About the Grams to Tablespoons — Cornflour / Cornstarch
Cornflour is a fine powder that settles hard in the box, so it is worth stirring before measuring. Because it is used in small quantities as a thickener, a proportional error here shows up quickly — a sauce thickened with 20% too much cornflour turns gluey rather than glossy. The same ingredient is called cornflour in the UK and cornstarch in the US, which is a common recipe trap. The figure this page works from is 120 g per US cup, the spooned-and-levelled weight recorded by King Arthur Baking and the USDA food database. Converting gram to tablespoon for cornflour / cornstarch, the amounts that come up most often are: 25 gram = 3.33 tablespoon; 50 gram = 6.67 tablespoon; 75 gram = 10 tablespoon; 100 gram = 13.3 tablespoon; 150 gram = 20 tablespoon; 200 gram = 26.7 tablespoon; 250 gram = 33.3 tablespoon; 500 gram = 66.7 tablespoon; 1000 gram = 133 tablespoon.
What people use it for
- Following a US recipe with a kitchen scale instead of cup measures.
- Scaling a recipe up or down without compounding measuring error.
- Converting a European recipe written in grams into cups.

The maths behind it
This tool uses tablespoon = gram × 0.1333333333, derived from cornflour / cornstarch weighing 120 g per US cup. Every intermediate value is shown on screen, so the result can be checked by hand.
Cornflour is a fine powder that settles hard in the box, so it is worth stirring before measuring. Because it is used in small quantities as a thickener, a proportional error here shows up quickly — a sauce thickened with 20% too much cornflour turns gluey rather than glossy.
Where this tool stops
Volume-to-weight conversion is inherently approximate. Humidity, brand, how finely something is milled and how long it has sat in the cupboard all shift the figure by a few per cent.
Frequently asked questions
Is cornflour the same as corn flour?
Not always, and this catches people out. In the UK, cornflour is the white starch thickener. In the US, "corn flour" can mean finely ground cornmeal, which is a completely different yellow ingredient. If a recipe uses it to thicken a sauce, it means the starch.
Why does a cup of cornflour / cornstarch not weigh the same as a cup of water?
Because a cup measures volume and a scale measures weight, and the two only agree for water. Cornflour / cornstarch has its own density — 120 g per US cup — so any generic volume converter gives the wrong answer here.
How much does the way I fill the cup matter?
Quite a lot. Cornflour is extremely fine and compacts readily, so a scooped cup runs well above the 120 g here. Since it is almost always used as a thickener in small quantities, the proportional error is what bites — a heaped tablespoon instead of a level one is the usual cause of a gluey sauce.
Is a US cup the same as a UK or metric cup?
No. A US cup is 236.6 ml, a metric cup is 250 ml and an old UK cup is 284 ml. These pages use the US cup, because that is what US recipes mean.
Are there any usage caps on the Grams to Tablespoons — Cornflour / Cornstarch?
There is no cost and no cap. The Grams to Tablespoons — Cornflour / Cornstarch is not a demo of a paid product, so nothing is held back or watermarked.
Does anything I enter leave my computer?
No. The Grams to Tablespoons — Cornflour / Cornstarch runs entirely in your browser using JavaScript. Because the work happens locally, the page also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What formula does the Grams to Tablespoons — Cornflour / Cornstarch use?
It uses tablespoon = gram × 0.1333333333, derived from cornflour / cornstarch weighing 120 g per US cup. The full working is printed under the result, so you can follow every step rather than trusting a black box.

What is the Grams to Tablespoons — Cornflour / Cornstarch used for?
Typical uses: following a US recipe with a kitchen scale instead of cup measures. Scaling a recipe up or down without compounding measuring error. Converting a European recipe written in grams into cups. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
When is the Grams to Tablespoons — Cornflour / Cornstarch not the right tool?
Volume-to-weight conversion is inherently approximate. Humidity, brand, how finely something is milled and how long it has sat in the cupboard all shift the figure by a few per cent. Knowing where a tool stops being trustworthy matters more than the cases where it works.
Which values should I know?
1 US cup of cornflour / cornstarch is 120 g. 1 Gram is 0.1333333333 Tablespoon. 1 Tablespoon is 7.5 Gram. These are printed on the page itself, so you do not have to take them on trust.
How precise is the result?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
