Use this page to help you to calculate the weights and calories of any serving size or portion of tomatoes, for various sizes and varieties.
The easy-to-use charts and calculator below will help you to calculate both cooking weight conversions and calorie amounts depending on what you need.
Because tomatoes are a natural product, weights vary vastly, from tiny cherry tomatoes to giant beefsteak. This makes it difficult to provide exact figures for all varieties, so to make things easier I’ve split this page up into size categories.
Because this page contains a large amount of information, you might find it helpful to use the table below to skip to the section you need:
