Grams to Cups Baking Conversion: Why 1 Cup of Flour ≠ 1 Cup of Sugar

By Xin He Jia · 2026-09-03

"One cup of flour" is baking's biggest trap: the same cup is 120 g of flour but 336 g of honey — 2.8× apart. A cup measures volume; density decides everything else.

Why the spread

Bulk density: sugar packs dense (200 g per cup), flour is fluffy (≈120 g, ±20% depending on how you scoop), honey traps no air (336 g). Cocoa at 85 g and almond flour at 96 g — a "cup of cocoa" and a "cup of almonds" are not the same quantity of anything.

How cups fail

What to do instead

Weigh. A kitchen scale costs less than a pizza and ends the problem: metric recipes copy straight, cup recipes convert with the table above. Tbsp/tsp columns are for spices, where spoons stay sensible.
