One level tablespoon (15 ml) of Flour weighs about 8 g. A teaspoon is around 3 g, a 200 ml cup around 110 g, and an everyday Korean rice spoon holds roughly 5.9 g level.
Flour is the ingredient most affected by how you fill the cup. Dipping the cup into the bag compacts it toward 130 g; spooning it in and levelling gives about 110 g. That gap is behind a lot of baking recipes that never quite work out.
Spoon it in lightly and level with a knife. Scooping straight from the bag packs it and can add 20%.

Measuring with a rice spoon or paper cup
A recipe tablespoon is 15 ml and a Korean recipe cup is 200 ml, but the spoon in your cutlery drawer holds about 11 ml level and a paper cup holds 180 ml. Measuring with everyday utensils therefore puts in roughly a quarter less than the recipe intends.
Heaping the spoon brings it close to a proper tablespoon. For salt, baking powder and anything else where a small error changes the outcome, use measuring spoons or a scale instead.
