Convert between cups, tablespoons, grams, and ounces for any recipe.
Converting Cooking Measurements
Recipes from different countries and sources use wildly different measurement systems — US cups and teaspoons, metric milliliters and grams, or imperial ounces. This calculator handles all three: volume-to-volume, weight-to-weight, and volume-to-weight conversions for common ingredients, where a cup of flour and a cup of honey weigh very different amounts.
Volume ⇄ Volume: convert through milliliters (ml) as the base unit
Weight ⇄ Weight: convert through grams (g) as the base unit
Volume ⇄ Weight: Weight (g) = Volume (ml) × Ingredient Density (g/ml)
Why Ingredient Density Matters
A cup of feathers and a cup of lead weigh very differently — the same is true in the kitchen. A cup of all-purpose flour weighs roughly 125g, while a cup of honey (which is much denser) weighs around 336g. That's why converting between volume and weight always requires knowing the specific ingredient's density, not just a generic conversion factor.

❓ Frequently Asked Questions
Why is a cup of flour a different weight than a cup of sugar? ▼
Different ingredients pack together with different densities depending on particle size, shape, and how tightly they compress — flour is light and airy compared to denser ingredients like sugar or honey, so equal volumes weigh different amounts.
Should I measure flour by weight or volume for baking? ▼
Professional bakers generally recommend measuring by weight (grams) whenever possible, since volume measurements like cups can vary significantly depending on how the flour is scooped and packed.
Are US and UK/metric cup sizes the same? ▼
No — a US cup is about 236.6ml, while some other countries (like Australia, UK legal cups) may use a slightly different standard, such as 250ml. This calculator uses the US customary cup measurement.
Why do liquid measuring cups and dry measuring cups matter? ▼
For pure volume-to-volume conversions it doesn't matter, but for measuring ingredients accurately, liquid measuring cups (with a pour spout) and dry measuring cups (leveled off flat) are designed differently to give accurate readings for each type of ingredient.
Can I add a custom ingredient not in the list? ▼
This calculator includes common baking ingredients with typical density values. For an ingredient not listed, you can look up its approximate density (grams per milliliter) and use the Weight ⇄ Weight or Volume ⇄ Volume modes with manual calculation as a workaround.
