A cup is a cooking measure of volume, primarily used in the United States. One cup is 240 millilitres (ml). Eventhough cups are used in other countries with varying measurements, most countries weigh non-liquid ingredients in grams, hence this website.

This website aims to provide help with converting measurements as found in your recipes or on food labels from and to cups, tbsp (tablespoon), tsp (teaspoon), oz (ounce) and grams.

Good to know:

  • cups on this page refer to the US legal cup, which is 240 ml
  • 1 cup is 16 tbsp or 48 tsp
  • 1 tbsp is 3 tsp
  • 1 tbsp usually is 15 ml in the UK and Canada, 14.8 ml in the US and 20 ml in Australia — this website assumes the British and Canadian standard and rounds numbers when considered convenient
  • oz on this page refers to the international avoirdupois ounce, which is approximately 28.35 grams and not to be confused with fl oz (fluid ounce )

In the table below you will find conversions from several volume measurements of products to their counterweight. Should you find any inconsistensies or think this page can be improved, please don't hesitate to provide feedback.
