Why sources disagree

Check whether the recipe means dry or cooked rice. USDA lists dry long-grain brown rice at 185 g per cup and medium-grain at 190 g. King Arthur Baking only lists cooked brown rice, at 170 g per cup, against USDA's 202 g: cooked rice packs loosely and holds more or less water, so the cooked figures vary most.

How to measure brown rice accurately

Use the Dry or Cooked setting to match what the recipe lists.
Weigh dry rice before rinsing and cooking so the amount stays consistent.
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.
