In a scientific context, 'Precise' can be considered the number of digits you use to refer to a number. Accurate refers to how close that number is to the real value. 1.05 mm is much more precise than 1 mm. If you measure a 7.5 mm item, and report it as 10 mm, you are not very accurate.

Hi Robinson, The two words are similar, but have some differences in usage. 'Accurate' is another way of saying 'Correct'. For example, information can be accurate. If it's not accurate, then it's wrong. 'Precise' is another way of saying 'Specific' or 'Exact'. For example, information can be precise. If it's not precise, then it's not clear - it's general and unspecific. I hope that helps. Jonny

Very little. Commonly they are used to mean the same thing.
