Why sources disagree

Oil is lighter than water, so a cup weighs less than a cup of water (236.6 g). USDA's 216 g comes with matching spoon figures, 13.5 g per tablespoon and 4.5 g per teaspoon. King Arthur's chart rounds a quarter cup to 50 g, and multiplying that up to a cup gives the 16 g gap.

How to measure olive oil accurately

Weigh oil straight into the bowl to skip the oily measuring cup.
Use a clear liquid measuring cup on a flat counter and read it at eye level.
If you use cups, fill the same way every time so your results stay consistent.

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.
