Build a mind you’re proud of.

Human intuition is poor at huge scales

We understand differences like ten versus twenty, but struggle to feel the gap between a million and a billion.

The idea

A million is 1,000 thousands. A billion is 1,000 millions—three extra zeros that create a thousandfold difference.

An example

One million seconds is about 11.6 days. One billion seconds is about 31.7 years.

Put it into practice

Translate very large numbers into time, distance, or per-person amounts before judging their meaning.

Test yourself: A billion is how many millions?

1,000

Correct. Those three extra zeros make a billion one thousand times a million.
