So I can estimate how much sugar to put in cup. I can estimate what time it is by looking at the sun. I can guess someone's weight or height, even though I haven't actually measured it. An estimate can be an opinion that has some rational basis. I can look at a painting and estimate what it might sell for, basd on my experience.
