Why sources disagree

King Arthur lists most liquids and soft dairy at 227 g per cup, which is 8 ounces by weight. USDA's 245 g comes from measured portions of plain whole-milk yogurt, which is the figure we use. Thick Greek yogurt is denser and can weigh more per cup.

How to measure plain yogurt accurately

Stir the yogurt smooth before you measure it.
Weigh on a digital scale when you can, since it skips the mess of measuring cups.
Use a clear liquid measuring cup on a flat counter and read it at eye level.

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.
