Free-form entry eg: '125000km', '1.5 million inches', '$67bn', '45000000 AUD', 100years', '123456789', '1 trillion', '1.5e6', '25 million kg'

Visualising 1 in a million

Cute video featuring nine ways to visualise 1 in a million. Interesting that five of the nine ways involve the use of an intermediate grouping. For example, 100 people have an average of 100,000 hairs on their heads. 10 hairs represents 1 in a million. 4 of the comparisons are direct, eg 1 word in all of the text of the Harry Potter novels.

Numb about Numbers?

In 1982 Douglas Hofstadter wrote about Number Numbness. We’re still befuddled in the face of millions and billions, let alone trillions or even bigger numbers.

That’s the reason for IsThatABigNumber.com: to help anyone develop their number sense by putting big numbers in context and providing meaningful comparisons.

Logs: Level-Up your Number Sense

This article about log scales and how to think about them (and how they naturally reflect how we think about big numbers) pretty much nails it, for me. Using log scales is an essential tool in your mental numeracy toolbox.
