It is important to get both accurate and precise answer because they are considered close to the accepted value of something. Preciseness, on the other hand, shows that the data collected are close to each other.
If you make rough or approximate measurements when doing experiments , you will get a rough and approximate answer, won't you!. For any information to be useful, it must be accurate and reliable. What would happen if bridge designers used the results of steel strength tests, which were approximate or just slightly wrong? ANSWER: there would be either, far too much expensive steel used to make the bridge, or there would be a slight mishap, such as a few dozen loaded trucks falling into the river. If you are a Scientist or a design Engineer, you must be thorough and very very accurate with everything you do. People that manufacture things , such as Medicines, and Cars, and Clothing, and Houses, and anything you can think of; must measure, or weigh everything very very accurately otherwise people die. Sloppy workers and rough careless workers are useless and dangerous people, and they can cause the death of innocent people.
Precision is very important when measuring anything for accuracy purposes. If your measurements are not accurate, your results may not be reliable.
Accuracy, precision, repeatability and so on are terms that have been closely defined for measurement purpose. By folk such as ASTM. and ISO.The true value is the value towards which a large number of different measurements (by different measurement teams, using different measuring systems ... ..) tends.The accuracy of a particular method or measurement is how closely that answer comes to the True Value.The precision of a measurement represents the confidence you have in the measurement. (Generally by making several measurements.)The resolution of a measurement is merely the number of figures in your answer. A number with many places would have greater resolution, but many of those numbers might be meaningless.So, a single measurement of the height of a mountain for example, might be correct, (true value) but you don't necessarily have reason to be confident of the answer.

Because if you add to much of that ingredient Like for example you add to much milk to pancakes it would be super watery so that is the reason why to be accurate ;D
The unit of measure, inches, cm, PSI, etc.
