What is the metric cup used for?

The metric cup is a volume unit defined as exactly 250 millilitres and is commonly used for measuring ingredient volumes in recipes, dietary specifications, and home cooking.

What does the tun measure?

The tun is a traditional English unit of liquid volume historically used to define large wine or ale casks, roughly equal to 954 litres, though its exact size has varied over time and region.

Why is the tun size variable?

The tun’s size has changed historically due to different regional definitions and changes in the gallon, so measurements from older sources may not match modern approximations.
