Cooking and Baking Conversions
Cooking conversions for teaspoons through gallons in one tool, plus the ingredient-specific weight converters that a single fixed ratio can't handle.
Most used cooking tools
Cups to Grams
By ingredient, because a cup of flour and a cup of honey don't weigh the same.
Ounces to Cups
Fluid and dry ounces handled separately.

Volume is easy, weight isn't
Everything in the tool above is a fixed ratio, because it is all volume. A cup is always 236.59 milliliters whatever is in it.
The moment a recipe gives a dry ingredient by weight, the fixed ratio disappears. A cup of flour and a cup of honey weigh very different amounts, so volume-to-weight needs the ingredient. That is what cups to grams is for, and why it has an ingredient selector rather than a single factor.
Which cup, and which tablespoon
This tool uses US customary measures. The US legal cup used on nutrition labels is 240 mL, the imperial cup is about 284 mL, and the Australian tablespoon is 20 mL against the US 14.79 mL. A recipe written in one system and measured in another will be out by a noticeable margin.
If a recipe's origin is unclear, weight is the safer route.
Common questions
How many tablespoons are in a cup?
Sixteen US tablespoons make one US cup, and there are 48 US teaspoons in a cup. These are fixed definitional relationships.
Why can this tool convert cups to milliliters but not cups to grams?
Because volume to volume is a fixed ratio and volume to weight isn't. A cup of flour and a cup of honey occupy the same space and weigh very different amounts, so a weight conversion needs to know the ingredient. That is what the cups to grams converter is for.
Is a US cup the same as a metric or imperial cup?
No. This tool uses the US customary cup of 236.59 milliliters. The US legal cup used on nutrition labels is 240 milliliters, and the imperial cup is about 284 milliliters.
Is an Australian tablespoon different?
Yes. The Australian tablespoon is 20 milliliters against the US 14.79 milliliters, which changes how many fit in a cup. If a recipe's origin is unclear, weighing is the safer route.
