Grinding removes the gaps between whole spices, so grinding one spoonful of whole spice produces more powder than the original measure holds. The difference appears in the reference measurements: a tablespoon (15 ml measure) of whole black pepper weighs 9 g, while the same measure of ground black pepper weighs 7 g. In other words, measuring before or after grinding does not give the same amount.
Grinding whole spices just before use preserves their aroma, but it raises a measurement question: should you measure before or after grinding? These two amounts are not the same. Whole seeds pack loosely, with visible gaps between them; when ground, those gaps close and the same material fits into a smaller volume. In other words, one spoonful of whole spice produces more powder than the original measure holds when ground, and the difference is not negligible. So the benefit of freshly grinding spices for aroma brings us back to the measurement question.
The difference is clear in the standard reference measurements. One tablespoon (15 ml measure) of whole black pepper weighs 9 g, while ground black pepper placed in the same measure weighs 7 g. The 2 g difference is the space between the peppercorns that the spoon contains. As a proportion, the spoonful of whole pepper weighs roughly one-quarter more. So if a recipe calls for one spoonful of whole black pepper and says to grind it, the resulting powder will exceed that spoonful, and that extra amount directly affects the dish’s pungency. Because black pepper is dominant even in small amounts, this difference is directly noticeable in the dish.
The same relationship applies to other spices, but the proportion varies because the shape of the pieces matters. Round, smooth seeds pack closely into a spoon, leaving little space. Hollow seeds such as coriander seeds occupy much more air space in a spoon, and their volume drops substantially when ground. Measuring cinnamon sticks and bark spices by spoon is not meaningful; measure them by count or weight instead. For that reason, there is no single correction factor. The grind size matters too, because coarsely ground spices take up more space than finely ground ones.
The recipe wording tells you how to read the measure. “One 4 ml tea-spoon measure of ground black pepper” means measure it after grinding; whatever amount is ground, fill the measure at the end. “One 4 ml tea-spoon measure of whole black pepper, ground” means measure the whole pepper first and then grind it. The two sentences look alike but specify different amounts. Looking at where the adjective appears is the simplest way to correct a spice measurement. If you are unsure which of the two wordings is intended, choosing the smaller amount is safer than choosing the larger one.
Weighing removes the uncertainty entirely. When a spice is given in grams, whether it is whole or ground does not change the measured amount; grinding changes only its volume, not its weight. Because the amounts are small, the scale’s resolution can be a problem; in that case, grind a larger amount, divide it, and store the remainder in a sealed container. Ground spices quickly lose their aroma, so keep this storage brief and prepare only enough for the next dish. This preserves the aroma and removes the measurement question.

Karabiberde dokuz gram ölçüsü elimde bir dayanak oldu, değirmenle çalışırken tartıya bakıyorum artık.
Öğütünce hacmin artması sezgiye ters geliyor ama boşluk açıklamasıyla oturuyor.
Ben hep öğütülmüş hâlini ölçüp sonra taneyi ona göre koyuyordum, tam tersini yapıyormuşum. Bu yüzden kimyon ve karabiberim tariflerde hep fazla çıkıyordu. Şimdi taneyi tartıp öğütüyorum, ölçü ne kadar toz çıktığından bağımsız oluyor.
