In detail: Sugar to Teaspoons Calculator for 20g of Sugar

20g of sugar is about 5 teaspoons. The NHS daily limit for added sugar is 30g (about 7.5 tsp) for adults. That's the core number — but the useful context is how sensitive it is to the inputs. Change any one of the assumptions by even 10–20% and the final figure can move meaningfully, which is why a calculator like this is better than a rule-of-thumb memorised from a magazine article.

Looking at the alternate scenarios below, the spread tells you how robust (or fragile) your answer is: if small changes produce big swings, plan for the pessimistic case; if it's stable across the range, you can commit more confidently.
