Why sources disagree

Coconut flour is fine and packs easily, so a spooned cup and a scooped cup can differ, which helps explain the 16 g gap. Bob's Red Mill's figure comes from a 2-tablespoon label serving, and multiplying a small serving up to a cup also magnifies its rounding. Coconut flour soaks up far more liquid than wheat flour, so do not swap it cup for cup in a recipe written for all-purpose flour.

How to measure coconut flour accurately

Whisk out lumps, then spoon the flour into the cup instead of scooping.
Use coconut flour only in recipes written for it, since it absorbs much more liquid than wheat flour.
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.
