Why sources disagree

The two figures are only 3 g apart. Sour cream is thick, so it can trap air in the cup; spoon it in and press it down, or weigh it straight into the bowl.

How to measure sour cream accurately

Scrape the cup clean with a spatula, or weigh the sour cream into the bowl.
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.
