To convert grams of tomato sauce into tablespoons, multiply by 0.065306122: one gram comes to 0.065306122 tablespoons. Every ingredient has its own figure here, because the units are measuring different things and only the density links them.
The density behind that figure is 1.0356 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of tomato sauce weighs 245 g, so this ingredient is 103.6% as heavy as the same volume of water — the single fact the whole page rests on.
A level tablespoon of tomato sauce is 15.31 g, which puts a teaspoon at 5.104 g and a tablespoon and a half — the quantity recipes are fondest of — at 22.97 g. Levelling twice is where the error comes from, so the scale is the faster instrument once the quantity passes a couple of spoons.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.408% of a cup of tomato sauce, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.041 cups, and a 1 kg pack 4.082.
What the number depends on: Plain passata or smooth sauce, not paste. Concentrated tomato paste is considerably heavier per cup because most of the water has been driven off, so the two are not interchangeable by volume.
The formula
grams- The amount of tomato sauce you are converting, in grams
0.065306122449- Tablespoons per gram for tomato sauce, from its density of 1.0356 g/mL
tablespoons- The equivalent quantity in tablespoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.065306122449, the tablespoons-per-gram figure for tomato sauce.
- The result appears in tablespoons, with a second reading in tsp beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
50 g of tomato sauce in tablespoons

150 g of tomato sauce in tablespoons
150 g of tomato sauce weighs out at 9.79592 tablespoons. Divide 9.79592 by 0.065306122 and you get back to 150 g, which is the quickest check that the factor is the right way up.
500 g of tomato sauce in tablespoons
500 g of tomato sauce weighs out at 32.6531 tablespoons. Divide 32.6531 by 0.065306122 and you get back to 500 g, which is the quickest check that the factor is the right way up.

Frequently asked questions
How many tablespoons are in 1 g of tomato sauce?
One gram of tomato sauce is 0.065306122 tablespoons. Half that quantity is 0.0326531 tablespoons and double it is 0.130612 tablespoons, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of tomato sauce not 236 g like water?
Because weight per cup depends on what is in the cup. Tomato sauce has a density of 1.0356 g per mL where water has 1.00, so a cup of it weighs 245 g rather than 236.6 g. That is a difference of 8.4 g per cup, and it is the reason a single volume-to-weight factor cannot be applied to every ingredient.
Does how I measure it change the weight?
Barely. Tomato sauce does not compress, so a cup of it is 245 g however it is poured — within about 1%, which is inside the accuracy of a domestic scale. This is the group where measuring by volume is defensible.
Is a fluid ounce of tomato sauce the same as an ounce?
No. A fluid ounce is a volume — one eighth of a US cup, 29.57 mL — and an ounce is a weight. One fluid ounce of tomato sauce weighs 1.08 oz, so the two readings differ by 8.03%. They coincide only for something with the density of water, and then only roughly.
Is this a US cup or a metric cup?
US customary: 236.59 mL, which is the cup every US recipe means. A metric cup is 250 mL, so the same cup of tomato sauce would weigh 258.89 g instead of 245 g — 13.9 g more, or 5.67%. Australian and some European recipes use the metric cup, and the difference is large enough to matter in baking.
Do I need a scale for this, or will measuring cups do?
A scale, if the result matters. Volume measuring carries a spread of about 1% for tomato sauce — roughly 2.45 g on a 245 g cup — while a domestic scale is accurate to a gram or two. For anything where the ratio of ingredients drives the outcome, bread and pastry above all, weigh it.
How much does 3 tbsp of tomato sauce weigh?
3 tbsp of tomato sauce comes to 45.938 g, or 45.938 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the tablespoons-to-grams page does it in the direction the question is usually asked.
