One gram of tahini is 0.0041666667 cups, so converting grams of tahini to cups means multiplying by 0.0041666667. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
Water is the yardstick: 1 mL of it weighs 1 g. Tahini comes in at 1.0144 g per mL, or 101.4% of water, which is why a cup of it is 240 g rather than 236.6 g. Volume and weight only line up for water, and only in metric.
A cup of tahini is 240 g when it is measured the standard way, but how it gets into the cup changes the answer: between about 238.8 g and 242.4 g covers the range from lightly spooned to firmly packed. That 1% spread is larger than most of the adjustments recipes fuss over, and it disappears entirely the moment the ingredient is weighed instead.
Grams are the unit this conversion is really for. A domestic scale resolves to a gram, which is 0.417% of a cup of tahini, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 2.083 cups, and a 1 kg pack 4.167.
How the figure is arrived at: Well stirred. Sesame paste separates in the jar and the oil that rises is the lightest part of it.
The formula
grams- The amount of tahini you are converting, in grams
0.00416666666667- Cups per gram for tahini, from its density of 1.0144 g/mL
cups- The equivalent quantity in cups
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.00416666666667, the cups-per-gram figure for tahini.
- The result appears in cups, with a second reading in tbsp 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 tahini in cups
Take 50 g of tahini: 50 × 0.0041666667 gives 0.208333 cups. Doubling the batch takes it to 0.416667 cups, because the relationship is a straight proportion once the density is known.
150 g of tahini in cups
150 g of tahini weighs out at 0.625 cups. Divide 0.625 by 0.0041666667 and you get back to 150 g, which is the quickest check that the factor is the right way up.
500 g of tahini in cups
Take 500 g of tahini: 500 × 0.0041666667 gives 2.08333 cups. Doubling the batch takes it to 4.16667 cups, because the relationship is a straight proportion once the density is known.

Frequently asked questions
How many cups are in 1 g of tahini?
One gram of tahini is 0.0041666667 cups. Half that quantity is 0.00208333 cups and double it is 0.00833333 cups, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of tahini not 236 g like water?
Because weight per cup depends on what is in the cup. Tahini has a density of 1.0144 g per mL where water has 1.00, so a cup of it weighs 240 g rather than 236.6 g. That is a difference of 3.4 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. Tahini does not compress, so a cup of it is 240 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 tahini 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 tahini weighs 1.058 oz, so the two readings differ by 5.82%. 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 tahini would weigh 253.61 g instead of 240 g — 13.6 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 tahini — roughly 2.4 g on a 240 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 2 cup of tahini weigh?
2 cup of tahini comes to 480 g, or 480 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the cups-to-grams page does it in the direction the question is usually asked.
