Grams of Flour to Cups

How many cups a weight of all-purpose flour makes, and how much that changes if the cup was dipped rather than spooned.

With amount 1, grams to cups converter comes to 120 — converted. It is reached in 9 steps, the last of which is to_volume_share == 0 ? grams / to_mass_share : cups / to_volume_share, and each one is printed on the page with its numbers filled in. The formula is the one published by King Arthur Baking, not an approximation fitted to it.
