Why weight matters: 2/3 cup of sea salt (fine) can weigh anywhere from 159g to 224g depending on how you measure it. The USDA standard is 186.67g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About sea salt (fine) density: Fine sea salt is similar in grain size to table salt. 1 teaspoon fine sea salt ≈ 5-6g. Coarse sea salt is much lighter per teaspoon (like kosher). Sea salt contains trace minerals that table salt does not. 1:1 fine sea salt = table salt.
About 2/3 Cup as a Measurement
2/3 cup = 10 tablespoons + 2 teaspoons = 160ml. This measure appears when scaling up 1/3 cup recipes by doubling. Use two 1/3-cup measures for accuracy, as 2/3 cup sets are less common.
Two-thirds cup is often seen in oatmeal cookie recipes, breakfast grain bowls, and rice cooker recipes for 2 servings. It equals exactly 160ml or approximately 5.4 fluid ounces.
