Accuracy is being close or on target most of the time precision is 100% on every time. A triple beam balance will be accurate but not very precise. It will get you close but not to the hundredth of a gram were the electronic balance is very accurate and precise were it can get you in the hundredth of a gram and will be right. A significant digit can be a number such as 384,238. It can be a number split at the decimal such as 43.2309. The only time the hole number is not significant is in this case 0.00004 the underlined 0's are not significant. From our data 2 Liters of water is 2,000,000 mm of water.
