As of 13 August 2026, AI can convert a recipe into grams.
This still needs a person who signs their name to it.

What the alternative costsThe practical alternative is a kitchen scale, with ingredient packaging or a reliable recipe source for checking.
If this goes wrong, the recipe may be too wet, dry or otherwise unbalanced and you can correct it before serving by checking the quantities and adjusting the batch.
What to actually do
Hand it to a person
The route this page recommends
A person who owns the outcome does this end to end, worth it when the failure is dear.
Do it yourself
Second choiceA chat interface, no skill needed, and roughly 15 minutes until you can act on the result.
How to actually do it
- Open the recipe and copy the full ingredient list, including the stated portions, preparation descriptions such as chopped or packed, and any quantities given in cups, tablespoons or teaspoons.
- Paste the recipe into a chatbot with the conversion prompt above and state the required number of portions if it differs from the original.
- Ask the chatbot to return a table with the original measure, ingredient, gram amount and assumption for each line.
- Open the ingredient packaging or the recipe source and compare the chatbot's ingredient names, quantities and preparation descriptions with the original.
- Put the ingredients marked as uncertain on a kitchen scale, using the stated preparation and packing method, and replace the estimates with your measured weights.
- Save the checked gram-based ingredient list with the portion count before cooking, and check food labels separately if allergies, intolerances or a medically prescribed diet are involved.
Prompt
Convert the recipe below into grams for a UK kitchen. Keep the same number of portions unless I specify a different number. For every ingredient, show the original quantity, the converted gram amount and any assumption you made. Use ingredient-specific estimates rather than treating all cups, tablespoons or teaspoons as having the same weight. Separate dry ingredients, liquids and ingredients whose weight depends strongly on how they are packed or prepared. Flag any conversion that cannot be reliable without weighing that ingredient directly, and do not invent missing quantities. Do not change the recipe, substitute ingredients or give nutrition or medical advice. If the recipe is intended for a medically prescribed diet or an allergy-sensitive person, say that the ingredient list and suitability must be checked separately. Recipe: [paste recipe here]

What it gets wrong
- AI cannot know how tightly flour, sugar or other ingredients were packed in the original measuring cup.
- AI cannot weigh an ingredient that varies substantially by size, moisture, brand or preparation.
- AI cannot confirm that a conversion is suitable for an allergy, intolerance or medically prescribed diet.
- AI cannot rescue a recipe whose original quantity or ingredient description is missing.
- AI cannot replace a kitchen scale when a precise result matters.
Even on a YES, the friction has a name: judgement under ambiguity, verification cost and stakes of error.
How we scored this
Five axes, each scored nought to two by hand: ten means AI carries the task cleanly, and the thresholds that turn a total into YES, PARTLY or NO are published in the methodology. Each axis name links to its definition.

FAQ
- Can AI convert cups to grams?
- Yes, for many common ingredients, but the result is an estimate rather than a universal conversion. Ask for an ingredient-specific weight and check uncertain amounts with a kitchen scale.
- How accurate is AI at converting a recipe to grams?
- It can handle the arithmetic and produce a useful starting point, but accuracy depends on the ingredient, how it was packed and whether it was chopped or prepared. Check the result against packaging or weigh the ingredient directly when the recipe is sensitive to proportions.
- Can ChatGPT convert a UK recipe to grams?
- Yes. Paste the complete recipe and ask it to preserve the portions, explain its assumptions and flag estimates for ingredients whose density varies.
- Can AI convert tablespoons and teaspoons to grams?
- Yes, when the ingredient is named clearly. A tablespoon of one ingredient does not have the same weight as a tablespoon of another, so verify important or uncertain conversions with a scale. If you have urgent or worrying symptoms, contact NHS 111 at https://111.nhs.uk or call 111 rather than relying on AI, which cannot diagnose.
