Which Is Actually Bigger?
Enter any area, volume, weight, length, or time and compare it against things that are easier to picture.
Enter an amount to see comparisons.
Numbers in the billions and trillions are technically precise and practically meaningless to most people.
The human brain has no intuition for large quantities. "2.6 million square kilometres" is a fact; "roughly the size of 364 million football pitches" is something you can almost feel. This tool converts quantities into comparisons against things that already have some shape in your head — not because it is more accurate, but because it is more comprehensible.
Questions
How accurate are the reference sizes?
Reference values are approximate averages. A football pitch varies slightly between grounds; an Olympic pool has a defined volume but depth varies. These comparisons are for illustration, not precision measurement.
Why Wales?
Because comparing large areas to Wales is a proud tradition of British science journalism, and we are not going to be the ones to break it.
