The accuracy of electronic scales for weighing gold is generally one ten thousandth of the accuracy of electronic scales, so that accurate things can be weighed.

When the quantity of gold ornaments reaches 0.0 1g, it must be equipped with second-class or first-class balance. Only when the sky level reaches one thousandth can the percentile error not exceed 0.01g.

Individual gold stores have now marked 0.00 1 g, so the balance must be a first-class balance of 10,000 digits.

Gold, masonry, silver and jewelry are all expensive, so it is inevitable that there will be errors when weighing by percentile or thousandth, because the accuracy of percentile balance and thousandth electronic balance can not meet the requirements.
