Nuts are one of my favorite snacks, and they’re full of good things. But the calories in nuts can rack up, and if you’re keeping an eye on such things, it’s helpful to know just how many nuts fit into 100 calories.

Pistachios, peanuts, almonds, cashews — here’s a guide to the 100-calorie serving of nuts.

100 Calories of Almonds

I measured roasted, salted almonds, which, depending on whether oil was used in roasting or not, should contain roughly the same amount of calories per gram as raw almonds.

  • Weight: 17 to 18 grams
  • Volume: About 15 to 19 almond kernels

100 Calories of Cashews

I checked raw cashews. Roasted cashews sometimes have more calories per gram, due to oil used in the roasting process.

  • Weight: 18 grams
  • Volume: About 13 to 14 whole cashews

100 Calories of Peanuts

Peanuts are so easy to snack on, but two scant tablespoons will get you to 100 calories right quick. I measured roasted, salted peanuts.

  • Weight: 17 grams
  • Volume: About 2 tablespoons

100 Calories of Pecans

Pecans surprised me — they are more calorie-intensive per gram than any of the other nuts I measured.

  • Weight: 14 to 15 grams
  • Volume: About 10 pecan halves

100 Calories of Pistachios (Shell Off & Shell On)

Who eats shelled pistachios? I hardly ever do — I buy them with the shells on for economy and freshness. So I checked them both ways, with shells and shelled.

  • By Weight: 18 grams (shelled) or 40 grams (unshelled)
  • By Volume: About 28 nuts (shelled) or heaping 1/3 cup (unshelled)
