A metric cup (250 ml, used in Australia, New Zealand, Canada and many Indian recipes) holds about 6% more than a US cup.
Liquid oils are measured in a liquid measuring cup at eye level. Solid fats are pressed into the cup with no air pockets.
Weights are for a level US cup (236.6 ml) and level spoons, from USDA FoodData Central household measures. Brands and packing vary by a few per cent; when a recipe gives grams, weigh rather than measure.
1 level US cup of peanut butter weighs about 258 g (9.1 oz). A 250 ml metric cup weighs about 273 g.
1 level tablespoon of peanut butter is about 16 g, and 1 teaspoon is about 5.4 g.
100 g of peanut butter is about 0.39 cups, or 6.2 tablespoons.
A cup measures volume, not weight. Peanut Butter is denser than water, so a cup weighs more (258 g vs 237 g).
