They are so big you could fit a train in them. Oh, wait...

By the industry standard unit of measure, shouldn't that be, "you could
drive a London double-decker bus through those"?

And I wonder if you could?

How do they compare with the size of Wales?

Wales is the standard unit of measurement for large areas, such as rain
forests or provinces (football fields and tennis courts are used for
smaller areas). London buses are the standard unit for height (for much
smaller objects, human hairs are the unit).


Nelson's Column is used for bigger sizes

And, of course, Olympic-sized
swimming pools are used for volume comparisons.




Elephants are used for both weight and volume.


St Paul's Cathedral seems to be both a height and a volume
measurement.
How many Elephants do we need before we change to Albert Halls.


Via blue whales.
