About this site

ConvertBite converts kitchen measures by ingredient — grams and cups of flour, sugar, butter and more — and one unit into another, and shows the number it used, with the official source that number comes from. Every page is meant to load in one trip and work without asking you for anything.

Who makes it

It is built and maintained by Javier Miralles, at EasyByte Hub S. Coop. Mad., a software co-operative based in Spain. Write to contact@easybyte.es if a factor looks wrong — that is the message we most want to get.

Where the factors come from

A conversion factor is either exact by definition or it is someone's rounding, and the two are not the same thing. The factors on this site are taken from NIST Special Publication 811, Appendix B, which lists them to the precision it publishes and marks which ones are exact by definition. They are read from that table, not copied from another converter — and each page links it, so you can check the one you are using.

Grams and cups are a different case: they only convert once you know the ingredient. The weight of a US cup of each ingredient is taken from USDA FoodData Central, the food composition database of the US Department of Agriculture, and every kitchen page names the FDC ID of the food record it was read from. An ingredient without a record there does not go on the site.

Cooking times by weight — turkey, ham, beef roasts — are the charts of USDA Food Safety and Inspection Service (FSIS), copied as printed, with the date each chart was read and the date FSIS last updated it. Each of those pages names its chart and links it; a copy of the chart as read is kept so the next yearly check can compare.

Sources and corrections

Every figure on this site comes from a cited primary source — NIST for units, USDA FoodData Central for ingredients, USDA FSIS for cooking times — and each page names it. Javier Miralles is responsible for the content, and any error reported to contact@easybyte.es is corrected.

What we will not do

• Publish a factor we cannot source. A converter that is confidently wrong is worse than none.
• Ask for your email before showing you the answer.
• Load a font, a framework or a tracker that slows the page down for our convenience.

Corrections

If a number is wrong, tell us and we will fix it and say what changed.
