One tablespoon holds 14.79 grams of water.
I bought a new set of measuring spoons. The top one holds 14 grams of water. I added water to the point where the spoon would spill over if I added any more. It's the new one. The bottom one is the old tablespoon. It would only hold 12 grams from the same water source. I've used the bottom spoon for many years and all this time I have been using a tablespoon which, in fact, has been out by almost three grams. That doesn't sound like much but if you are measuring out say ten tablespoons that amounts to about 30 grams. No wonder sometimes things don't turn out as expected.
