How do I convert cups to US cups for any recipe?

Switching between metric cups and US cups is a fixed volume ratio that applies to any ingredient, since one US cup is 240 ml and one metric cup is 250 ml. The volume converter at the link below covers cups, US cups, millilitres, tablespoons and teaspoons in both directions.

What is the difference between a metric cup and a US cup?

A metric cup holds 250 ml while a US cup holds 240 ml, so a US cup is 4% smaller. For chopped tomato that gap is small but real, and it adds up across several cups. The guide linked below explains when the difference matters and how to switch between the two so a recipe lands right whichever cup you own.

Tomato varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common tomato varieties compare.

Variety	Best for
Roma	Sauces, roasting, and slow-cooked dishes; low moisture and few seeds mean it breaks down cleanly.
Cherry	Salads, roasting whole, and snacking; naturally sweet with thin skins.
Beefsteak	Slicing for sandwiches and burgers; large, meaty slices with a mild flavour.
Heirloom	Fresh eating and salads; complex flavour and striking colour, best uncooked.
Grape	Snacking, lunch boxes, and quick salads; similar to cherry but firmer and oblong.

Which should I pick?

Roma is the best choice for sauces and cooking, with firm, low-moisture flesh that holds up well to heat. Use Beefsteak or Heirloom when you need thick slices for fresh eating; Cherry or Grape work well for snacking and salads.
