About CookScale

CookScale started with a simple frustration: the numbers cooks find online are either wrong, vague, or copied from one site to the next without anyone checking them.

Ask the internet how many grams are in a cup of flour and you will get 120, 125, 130 and 142 grams — all stated with equal confidence, none of them saying how the cup was filled. Ask how to substitute butter with oil and you will get a ratio with no mention of what happens to the texture. Ask how to double a cake and you will get “just double everything” — advice that has ruined more cakes than any oven ever has.

CookScale does it differently. Every converter on this site is built on published density data — the King Arthur Baking ingredient weight chart and USDA FoodData Central — and every result says how it was measured: spooned and levelled, packed, or poured. Every guide says what changes in the result, and when not to substitute at all. You can read exactly how we work in our Editorial Policy.

What we do

CookScale has two parts. The first is 32 free tools: cups to grams by ingredient, grams to cups, tablespoons to grams, recipe scaling, pan-size conversion, oven temperature, butter to oil, yeast, egg replacers, spice substitutes and more. Every tool runs entirely in your browser — nothing you type is sent to a server, and there is no sign-up.

The second part is in-depth guides: cups to grams for every ingredient, substitutions that actually work, pan-size conversions and recipe scaling, each one 1,200+ words, written to answer the real questions cooks ask — not to pad a page with keywords. The guides are being written ingredient by ingredient, and every one is checked against published sources before it goes live.

What we will never do

We will never present an estimate as a fact. A density-based result is a starting point, not a measurement — flour varies with brand, humidity and how the cup is filled, and every page on this site says so. We will never tell you a substitution is safe for an allergy without telling you to check the label yourself. And we will never sell your data — there is no account to create and nothing to sell. Read the Disclaimer and the Privacy Policy for the full picture.

Who is behind CookScale?

CookScale is a small, independent project run by people who bake and got tired of bad kitchen maths. We are not professional chefs, and we do not pretend to be — that is exactly why every page on this site cites its sources and tells you to verify with a scale. Our job is to make the published numbers easy to use and honest about their limits. If you spot a mistake, or a number you think is wrong, please tell us on the Contact page. We would rather fix a page than defend it.

Thank you for using CookScale — and may your next cake rise evenly. The Cups to Grams Converter is a good place to start.
