To convert grams of peanut butter into tablespoons, multiply by 0.062015504: one gram comes to 0.062015504 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 1.0905 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of peanut butter weighs 258 g, so this ingredient is 109.1% as heavy as the same volume of water — the single fact the whole page rests on.
A level tablespoon of peanut butter is 16.12 g, which puts a teaspoon at 5.375 g and a tablespoon and a half — the quantity recipes are fondest of — at 24.19 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 0.388% of a cup of peanut butter, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 1.938 cups, and a 1 kg pack 3.876.
How the figure is arrived at: Smooth, at room temperature. Straight from the fridge it is far harder to level into a cup, and that shows up on the scale.
The formula
grams- The amount of peanut butter you are converting, in grams
0.062015503876- Tablespoons per gram for peanut butter, from its density of 1.0905 g/mL
tablespoons- The equivalent quantity in tablespoons
How it works, step by step
- Enter the quantity in grams.
- It is multiplied by 0.062015503876, the tablespoons-per-gram figure for peanut butter.
- 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 peanut butter in tablespoons
Take 50 g of peanut butter: 50 × 0.062015504 gives 3.10078 tablespoons. Doubling the batch takes it to 6.20155 tablespoons, because the relationship is a straight proportion once the density is known.
150 g of peanut butter in tablespoons
A recipe calling for 150 g of peanut butter needs 9.30233 tablespoons on the scale. The arithmetic is 150 × 0.062015504 = 9.3023256, and halving the recipe halves the weight to 4.65116 tablespoons.
500 g of peanut butter in tablespoons
500 g of peanut butter weighs out at 31.0078 tablespoons. Divide 31.0078 by 0.062015504 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 peanut butter?
One gram of peanut butter is 0.062015504 tablespoons. Half that quantity is 0.0310078 tablespoons and double it is 0.124031 tablespoons, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of peanut butter not 236 g like water?
Because weight per cup depends on what is in the cup. Peanut butter has a density of 1.0905 g per mL where water has 1.00, so a cup of it weighs 258 g rather than 236.6 g. That is a difference of 21.4 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. Peanut butter does not compress, so a cup of it is 258 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 peanut butter 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 peanut butter weighs 1.138 oz, so the two readings differ by 13.8%. 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 peanut butter would weigh 272.63 g instead of 258 g — 14.6 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 peanut butter — roughly 2.58 g on a 258 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 peanut butter weigh?
3 tbsp of peanut butter comes to 48.375 g, or 48.375 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.
