Explanation

If you’re being imprecise, you’re not being exact. If you try to draw a perfect circle with your eyes closed, your drawing will probably be imprecise. One field where imprecise measurements can turn out to be troublesome is cooking. If you add an imprecise amount of flour into pizza dough, you will either get a crumbly, floury mess that won't stick together, or a big, gooey glob of dough that you can't roll out into a flat crust. Either way, your pizza will not turn out very well, and you might want to remeasure or order from the local pizza place!
