Which is insane. When the numbers become too large, they just stop making sense intuitively.
I had a nice comparison to put a billion into perspective : a million seconds is 11 days, a billion seconds is over 30 years. We understand these two durations reasonably well, and the difference can be "felt" clearly.
A trillion seconds is 30000 years... and again, the numbers stop making sense. That would be the Upper Palaeolithic. Agriculture was invented 10000 years ago. Hmm, what else ? Right, sorry, I rounded down. It would actually be 31688 years. A little slip-up of 1700 years, no biggie. The difference between today and the antiquity.
No, because I can picture 1 (dollar, apple, person, whatever) and 1000, and it's very obvious that one is a rounding error compared to the other, a difference of 0.1%.
It's just that I can't picture a million apples, much less a billion or a trillion. Hence why I usually turn to time, or distance.
Here's another : if a million is a kilometre, a billion is 1000km and a trillion is the distance to the moon and back.
