One gram of tahini is 0.033333333 fluid ounces, so converting grams of tahini to fluid ounces means multiplying by 0.033333333. That factor is specific to this ingredient — it comes from its density, not from any relationship between the two units.
The density behind that figure is 1.0144 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of tahini weighs 240 g, so this ingredient is 101.4% as heavy as the same volume of water — the single fact the whole page rests on.
This is the pair that catches people out. A fluid ounce is a volume and an ounce is a weight, and they are only the same number for something with the density of water. One fluid ounce of tahini weighs 1.058 oz, so the two readings differ by 5.82% — worth knowing before trusting a recipe that just says "oz".
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.
The condition this weight assumes: 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
0.0333333333333- Fluid Ounces per gram for tahini, from its density of 1.0144 g/mL
fluid ounces- The equivalent quantity in fluid ounces
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.0333333333333, the fluid ounces-per-gram figure for tahini.
- The result appears in fluid ounces, with a second reading in mL 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 fluid ounces
50 g of tahini weighs out at 1.66667 fluid ounces. Divide 1.66667 by 0.033333333 and you get back to 50 g, which is the quickest check that the factor is the right way up.
150 g of tahini in fluid ounces
Take 150 g of tahini: 150 × 0.033333333 gives 5 fluid ounces. Doubling the batch takes it to 10 fluid ounces, because the relationship is a straight proportion once the density is known.
500 g of tahini in fluid ounces
500 g of tahini weighs out at 16.6667 fluid ounces. Divide 16.6667 by 0.033333333 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 fluid ounces are in 1 g of tahini?
One gram of tahini is 0.033333333 fluid ounces. Half that quantity is 0.0166667 fluid ounces and double it is 0.0666667 fluid ounces, 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 3 fl oz of tahini weigh?
3 fl oz of tahini comes to 90 g, or 90 grams. This page runs that calculation in reverse — enter a weight and it returns the volume — and the fluid-ounces-to-grams page does it in the direction the question is usually asked.
