Why a Cup of Flour Isn’t a Cup of Flour
A cup of flour weighs 120 g spooned or up to 160 g scooped, and 92 to 163 g by type. Why one cup of flour is baking’s vaguest measure, and the fix.
Cooking guides, baking tips, conversion charts, and kitchen measurement advice.
The calculators on this site answer “how much?” and “what ratio?” — the blog answers “why?” and “what if?” These articles explain the reasoning behind the formulas, walk through real-world scenarios in detail, and cover topics that go beyond what a single calculator can address.
Articles on recipe scaling explain why spices, leaveners, and cook times do not follow the same multiplication rules as base ingredients. Measurement guides cover the practical differences between cups and grams, including variance data showing how much a single cup of flour can fluctuate depending on technique. Catering and event planning articles bring together multiple calculators into complete planning workflows — from per-person food quantities to oven scheduling.
Every article links to the relevant calculators so readers can apply what they learn immediately. Content is backed by the same sourcing standards as the tools: formulas verified against published references, density data from the FAO and USDA, and worked examples with checked arithmetic.

A teaspoon of table salt weighs about 6 g but of cinnamon just 2.6 g. Converting teaspoons to grams for spices, leaveners, and salt, where errors count.
Ingredient density explains why the same cup of flour, sugar, or honey lands on a different gram weight, and why serious baking is done by weight.
The fresh to dried herb ratio is 3:1, but the exceptions matter: woody herbs hold flavour, basil and parsley take more dried, and bay is its own case.
How sugar alternatives change a baking recipe: honey, maple, brown, and coconut sugar each shift moisture, browning, structure, and sweetness.
Buttermilk substitutes ranked for pancakes, cakes, and soda bread: kefir and thinned yogurt lead, milk-and-acid works in a pinch, plain milk fails.
The egg substitutes for baking that actually work, graded by job: flax and chia for binding, aquafaba for lift, banana and applesauce for moisture.
Substitute butter for oil at the right ratio both ways, with the cakes and quick breads where the swap works and the shortbread and pastry where it fails.
