Tomato converter: whole tomatoes, cups, grams

When a recipe calls for 2 cups of chopped tomato, you need roughly 3 medium tomatoes. A medium tomato weighs about 123 g, so larger or smaller specimens change the count noticeably. Select the size that matches what you have and the converter handles the rest.

Tomatoes range from small 91 g specimens to large 182 g ones, so a single cup of chopped tomato could come from one large tomato or nearly two small ones. Matching the count to your actual tomatoes keeps sauces and salads on target.

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.

VarietyBest for
RomaSauces, roasting, and slow-cooked dishes; low moisture and few seeds mean it breaks down cleanly.
CherrySalads, roasting whole, and snacking; naturally sweet with thin skins.
BeefsteakSlicing for sandwiches and burgers; large, meaty slices with a mild flavour.
HeirloomFresh eating and salads; complex flavour and striking colour, best uncooked.
GrapeSnacking, 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.
