To convert tablespoons of ground black pepper into grams, multiply by 6.875: one tablespoon comes to 6.875 grams. 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 0.46494 g per mL, against 1.00 for water. A cup of water weighs 236.6 g and a cup of ground black pepper weighs 110 g, so this ingredient is 46.49% as heavy as the same volume of water — the single fact the whole page rests on.
A level tablespoon of ground black pepper is 6.875 g, which puts a teaspoon at 2.292 g and a tablespoon and a half — the quantity recipes are fondest of — at 10.31 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 0.909% of a cup of ground black pepper, so weighing gets an accuracy no measuring cup can reach. A 500 g pack of it is 4.545 cups, and a 1 kg pack 9.091.
What the number depends on: Freshly ground is lighter per spoon than the pre-ground jar, which settles and compacts on the shelf.
The formula
tablespoons- The amount of ground black pepper you are converting, in tablespoons
6.875- Grams per tablespoon for ground black pepper, from its density of 0.46494 g/mL
grams- The equivalent quantity in grams
How it works, step by step
- Enter the quantity in tablespoons.
- It is multiplied by 6.875, the grams-per-tablespoon figure for ground black pepper.
- The result appears in grams, with a second reading in oz beneath it.
- Use the measure table if you want a standard recipe quantity rather than a number you type in.
Worked examples
2 tbsp of ground black pepper in grams
2 tbsp of ground black pepper weighs out at 13.75 grams. Divide 13.75 by 6.875 and you get back to 2 tbsp, which is the quickest check that the factor is the right way up.
4 tbsp of ground black pepper in grams
A recipe calling for 4 tbsp of ground black pepper needs 27.5 grams on the scale. The arithmetic is 4 × 6.875 = 27.5, and halving the recipe halves the weight to 13.75 grams.
12 tbsp of ground black pepper in grams
12 tbsp of ground black pepper weighs out at 82.5 grams. Divide 82.5 by 6.875 and you get back to 12 tbsp, which is the quickest check that the factor is the right way up.

Frequently asked questions
How many grams are in 1 tbsp of ground black pepper?
One tablespoon of ground black pepper is 6.875 grams. Half that quantity is 3.4375 grams and double it is 13.75 grams, so the figure scales straight up and down — there is no offset in this conversion, only the factor.
Why is a cup of ground black pepper not 236 g like water?
Because weight per cup depends on what is in the cup. Ground black pepper has a density of 0.46494 g per mL where water has 1.00, so a cup of it weighs 110 g rather than 236.6 g. That is a difference of 126.6 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?
Yes, and by more than most people expect. Handling changes the weight of a cup of ground black pepper by roughly 20% — about 11 g either side of 110 g — because freshly ground is lighter per spoon than the pre-ground jar, which settles and compacts on the shelf. Weighing removes the question entirely.
Is a fluid ounce of ground black pepper 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 ground black pepper weighs 0.485 oz, so the two readings differ by 51.5%. 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 ground black pepper would weigh 116.24 g instead of 110 g — 6.24 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?
At this size the spoon wins. One tablespoon of ground black pepper is 6.875 g, and a scale reading to the nearest gram is working at 14.5% resolution on that — a measuring spoon is the more accurate instrument below about 5 g, which is why spice quantities are still written in spoons.
How many tablespoons of ground black pepper is 500 g?
500 g of ground black pepper is 72.727 tablespoons — 0.145455 tablespoons to one gram, so 500 × 0.145455 = 72.727. Going that way is a division by 6.875, or a multiplication by 0.145455 if you prefer.
