Cooking Measurement Converter

Convert cooking measurements — cups, tablespoons, grams, ounces, millilitres — per ingredient, plus oven temperatures. Fast, private, client-side.

Converting between volume and weight uses the density of flour (all-purpose). Ingredients vary, so treat this as a close estimate, not a lab measurement.

Volume-to-weight conversions depend on the ingredient's density, so they are close estimates. US cups are used (1 cup = 236.6 ml). Everything is computed in your browser.

Convert recipe measurements between cups, tablespoons, grams, ounces, and millilitres — with the ingredient's density applied so volume-to-weight is right. There's also an oven-temperature converter for Celsius, Fahrenheit, and gas marks. Everything runs in your browser.

Volume vs. weight

Why a cup isn't a fixed number of grams.

Volume measures space; weight measures mass. A cup of flour and a cup of water fill the same space but weigh very different amounts, because flour is much less dense. That's why this converter asks for the ingredient when you cross between the two — it uses a typical density to translate. For consistent baking, professionals weigh ingredients in grams.

Oven temperatures at a glance

  • Gas mark 4≈ 180 °C ≈ 350 °F — the classic "moderate oven."
  • Gas mark 6 ≈ 200 °C ≈ 400 °F — hot, for roasting and many bakes.
  • Gas mark 1 ≈ 140 °C ≈ 275 °F — low and slow.

Frequently asked

Why do I need to pick an ingredient?
Converting between volume (cups, ml) and weight (grams, ounces) depends on how dense the ingredient is. A cup of flour weighs far less than a cup of honey. Choosing the ingredient applies the right density; converting within the same type (cups to ml, or grams to ounces) doesn't need it.
How accurate are the conversions?
Volume-to-weight results are close estimates — real densities vary with how you pack flour, the brand of sugar, temperature, and humidity. For baking where precision matters, a kitchen scale is still best; these numbers get you very close.
Which cup size does this use?
The US customary cup (236.6 ml). If you're following a recipe that uses metric or imperial cups, the difference is small but real, so weigh ingredients when it's critical.
