Why sources disagree

The two dry figures are 8 g apart. USDA lists raw lentils and raw pink or red lentils both at 192 g per cup, and Bob's Red Mill's 50 g quarter cup is a nutrition-label serving rounded to whole grams. USDA lists cooked lentils at 198 g per cup, so check whether the recipe means dry or cooked before converting.

How to measure lentils accurately

Use the Dry or Cooked setting to match what the recipe lists.
Pick over and rinse dry lentils after weighing them, not before.
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.
