About Grams to Cups
A free baking conversion site built on one idea: a cup of flour and a cup of honey are not the same weight, so every ingredient deserves its own number.
What we stand for
One ingredient, one number
Flour, sugar, butter and cocoa each get their own grams-per-cup value. We never run every ingredient through a single water-based ratio.
Sources you can check
Each ingredient page names its references, the measuring method behind the number, a confidence rating and the date we last checked it.
Free, no account
Every calculator, chart and article is free to use. There is nothing to sign up for and nothing to install.
Answers that load first
Results and tables arrive as plain HTML, so the answer is on screen before any script runs — even on a slow kitchen Wi-Fi connection.
Why we built this
Most online converters treat a cup as a fixed 240 milliliters and stop there — as if a cup of flour weighed the same as a cup of honey. It doesn't. We built Grams to Cups after one too many recipes went wrong because a generic converter didn't know the difference between a scooped cup of flour and a packed cup of brown sugar. Every ingredient on this site carries its own grams-per-cup value, so the numbers you get actually match what's in your mixing bowl.
Same cup, different weight
1 cup All-purpose flour
= 120g
1 cup Granulated sugar
= 198g
1 cup Butter
= 227g
How our data is made
We start from published baking references and standard kitchen measuring conventions, and record which method each number assumes: spooned, scooped or packed.
We cross-check similar ingredients against each other, so two kinds of sugar or two kinds of flour don't disagree for no reason.
Every value is published with its source, a confidence rating and a last-checked date. When we correct a number, it changes everywhere on the site at once.
Every entry is reviewed by a person before it's published; nothing on the site is generated from a formula without being checked. The full dataset is open to read on ouringredient weight data page.

Following an American recipe written in cups, or a European one written in grams, with whatever tools are in the drawer.

Turning a family recipe into weights for the first time, or scaling a recipe without a scale.
Food writers and bloggers
Checking that the cup and gram amounts in a recipe card actually match before it goes out to readers.
Culinary students

How the site is funded
Grams to Cups is free because it shows ads. Advertisers have no say in our data: no ingredient value, ranking or recommendation on this site is paid for. We also use analytics to see which pages are useful and where they're confusing. OurPrivacy Policy has the details.
Frequently asked questions
Is Grams to Cups really free?
Yes. There are no paid tiers, no paywall and no account. The site is paid for by the ads shown on its pages.
Why doesn't my result match the number in my recipe?
Recipe writers measure differently. A cup of flour that is scooped straight from the bag can weigh noticeably more than one spooned in and leveled. Each ingredient page tells you which method our number assumes, and a kitchen scale is always the most reliable answer.
Which cup do you use?
By default, a 240 ml US cup. The calculator can also switch to the 236.6 ml US customary cup or the 250 ml metric cup, and our cup sizes guide explains when each one matters.
Can I print or share your charts?
Yes, for your own kitchen. The printable charts are free to download and print for personal use. If you'd like to publish them on your own site, please ask us first.
What do I do if a number looks wrong?
Email us with the ingredient, the number you expected and how you measured it. We check every report against our sources and update the data when it's warranted.
