Measure flour the right way

Scooping flour straight from the bag packs it down and gives you a heavier cup. The 120 g value assumes the spoon and level method shown here:

Why only these ingredients?

A cup measures volume, a gram measures weight, and every ingredient has its own density. Recepti only converts cups to grams for ingredients with a well-established value, like the ones above. Everything else is converted to millilitres instead, so nothing is guessed.
