How this works in your browser
Every unit is defined by its exact ratio to a single base volume, so a value is normalised into that base and then divided back out into each unit. Routing through one canonical measure keeps every conversion consistent rather than maintaining a factor for each possible pair. The boundary worth being explicit about is that all of this is volume, and volume alone cannot give you weight: that conversion requires an ingredient's density, which varies by ingredient and, for flour especially, by how it was packed into the cup. That variability is the reason weight-based baking recipes exist, and the reason a generic volume-to-grams conversion would mislead.

Frequently asked questions
Are these US or metric cooking measurements?
US customary volume units (teaspoons, tablespoons, cups, etc.) alongside metric units (milliliters, liters), covering the most common recipe conversions.
Does 1 cup always equal the same amount worldwide?
This tool uses the US customary cup (about 236.6 ml). Some countries define a cup slightly differently - check your recipe’s origin if precision matters.
Can it convert dry ingredients like flour or sugar?
This converts volume only, not weight - dry ingredient conversions to weight vary by ingredient density and aren’t covered here.
Why can a cup of flour not be converted to grams?
Because volume and weight are different quantities and the bridge between them is density, which differs per ingredient. A cup of flour and a cup of sugar weigh very different amounts. Worse, a cup of flour weighs different amounts depending on whether it was scooped or spooned, which is exactly why serious baking recipes give weights.
Should I weigh ingredients instead?
For baking, yes, and it is the single biggest improvement most home bakers can make. Weight is unambiguous where volume depends on how tightly something packs. For cooking, where proportions are more forgiving, volume measures are perfectly adequate.
Is a UK cup the same as a US cup?
No. This uses the US customary cup of about 236.6 millilitres. Australian recipes use 250 millilitres and older British recipes may mean something different again, so a recipe's origin matters more than it appears when the quantity is large.
How do I scale a recipe up or down?
Convert everything to a single unit first, apply your multiplier, then convert back to practical measures. Doing it that way avoids the awkward arithmetic of thirds of a tablespoon, and it also stops small errors compounding across a long ingredient list.
