Precision is how exact a measurement is. To be more precise, you need to have more significant digits. Only decimals have significant digits. For example:
45.5653 ft
There are 4 significant digits because after the whole number, there are 4 numbers.
________________________________________________________
Accuracy is the closeness of a measurement to the actual value of what is being measured.
Some measurements can be accurate but not precise, and others can be precise but not accurate, Some can be neither, or even both.
