Why sources disagree

King Arthur lists most liquids at 227 g per cup, which is 8 ounces by weight. A US cup holds 236.6 mL, and cream's fat makes it close to water in weight, so USDA's 238 g is the figure we use. Whipped cream is mostly air: USDA lists a cup of whipped cream at 120 g.

How to measure heavy cream accurately

Measure cream cold and before whipping, since whipping adds air.
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.
