Kitchen Conversion Hub

About Kitchen Conversion Hub

A free, sourced set of kitchen converters that knows a cup of flour is not a cup of sugar.

Why this site exists

Most recipes written in the US measure by volume; most recipes written elsewhere measure by weight. The two do not convert with a single number, because a cup of flour, a cup of sugar and a cup of honey all weigh different amounts. Kitchen Conversion Hub gives you a converter that knows the ingredient, shows the source of every figure, and says plainly which cup it used.

What you will find

How we handle accuracy

We do not measure ingredients ourselves and we do not average numbers from random blogs. Each weight is a published figure from King Arthur Baking or USDA FoodData Central, and the line it came from is displayed on the sources page and beside every result. All other numbers, such as the grams in a tablespoon or the ml in a metric cup, are calculated from those figures and from standard unit definitions. Nothing is typed in by hand twice.

Weights are averages. A cup of flour can vary by more than 15 percent depending on how you fill it, which is the reason serious bakers weigh. The converter is a bridge for the times a recipe gives cups and you want grams, or the reverse.

Independence and updates

The site has no advertising, no sign-up and no tracking. It was last reviewed on 21 October 2026. If a figure on this site disagrees with the source it cites, trust the source and let us know through the channel you found the site from; we correct data errors as soon as they are confirmed.
