Why sources disagree

Salt grains differ in size and shape, so the same spoon holds different amounts. King Arthur lists 1 tablespoon at 18 g for table salt, 16 g for Morton kosher and 8 g for Diamond Crystal kosher. Swapping one for another by volume can double or halve the salt, so use grams.

How to measure salt accurately

Switch the brand setting before converting, since kosher salts weigh far less than table salt.
Salt is best weighed: a teaspoon of one brand is not a teaspoon of another.
Weigh on a digital scale when you can, since cup scoops vary from cook to cook.

Convert the whole recipe, not one line

Converting a recipe one ingredient at a time is where mistakes slip in. Sous Chef imports a recipe from a link or pasted text, then converts every ingredient at once: dry ingredients and butter to grams, liquids to millilitres. Tap again to go back to cups.

US recipe

2¼ cups all-purpose flour
1 cup butter, softened
¾ cup brown sugar, packed
1½ cups milk

In Sous Chef, after "Convert to metric"

275 g all-purpose flour
225 g butter, softened
170 g brown sugar, packed
350 ml milk

Example output. Sous Chef rounds to amounts you would actually weigh, so its numbers can differ by a few grams from the table above.
