Cooking Conversion Calculator

How this cooking conversion calculator works

Kitchen and recipe measurements are messy because different countries and sources use different systems (US customary, metric, UK imperial), and because food ingredients have different densities. This tool separates three scenarios:

1. Pure volume-to-volume (e.g. cups to ml) – exact, non-ingredient-dependent.
2. Pure weight-to-weight (e.g. grams to ounces) – exact and independent of ingredient.
3. Ingredient-aware conversions (e.g. 1 cup of flour to grams) – use a reference density.

Why conversions differ between websites

Competent cooking sources like AllRecipes, WebstaurantStore or The Spruce Eats often publish slightly different numbers. That’s because they choose different reference densities or round to user-friendly amounts. Here we show a professional, transparent approach ideal for food bloggers, chefs, developers of recipe apps and serious home cooks.

FAQ

1. Are US and metric cups the same?

No. A US cup is 236.588 ml; an Australian metric cup is 250 ml; UK recipes may refer to both. Always check the context.

2. Can I use this for baking?

Yes, but baking is sensitive. For consistent results weigh ingredients, especially flour, cocoa, sugar and fats.

3. What about packed brown sugar?

We used ~220 g per cup, which is common. But “firmly packed” or “lightly packed” can shift the weight; adjust when needed.

This section can host longer reference tables, like tablespoons per cup, ml per US fluid ounce, or typical densities for pantry staples. Keep it for users who scroll for deeper information.

• 1 cup = 16 tbsp = 48 tsp
• 1 tbsp = 15 ml (approx.)
• 1 fl oz (US) = 29.5735 ml
• 1 cup water ≈ 236.6 g (because water is 1 g/ml)

Volume: target = source_ml × (1 / target_unit_ml) Weight: target = source_g × (1 / target_unit_g) Ingredient (vol → wt): weight_g = volume_cups × density_g_per_cup Temperature: °F = (°C × 9/5) + 32 °C = (°F − 32) × 5/9 Gas Mark is estimated from °C intervals.
