Double-decker buses. Areas the size of Wales. Football pitches. Nelson's Column. Dan Burn.
We're all familiar with these standard conversational units of measurement, which helpfully allow lay people to put things into concrete terms they can easily imagine. Who even knows how big a square mile is? You don't. Stop pretending.
It was in that spirit that the BBC informed us during that fabulous 3-2 win over Mexico that the stadium was 1,114 Dan Burns above sea level, which of course we can all agree is 1) easy to conjure in the mind's eye, and 2) terrifying.

Hard Rock Stadium altitude in Dan Burns revealed at last
Dan Burn, of course, is the long-established everyday shorthand for six feet and seven inches, or 2.01 metres, if you want to be all new age about it.
You will have noticed this when visiting car parks in Newcastle, where helpful signage tells you that vehicles exceeding 1.4 Dan Burns in height should not try to enter.
From these principles, we can calculate precisely the altitude of Miami's Hard Rock Stadium in Dan Burns, ready to be cited when England take on Norway in the World Cup quarter-finals on Saturday.
The thing about Miami - some would say the main thing - is that it is very much a coastal city. And the thing about Florida is that it is very much flat.
The Hard Rock Stadium is only around 114 football pitches (1,077 double-decker buses) away from the Atlantic Ocean, to boot, making it an incredibly low-lying stadium indeed.
As a result, even the highest reasonable estimates for the stadium's altitude put it at just 1.97 Dan Burns above sea level.
If you wanted to mix your units between traditional British and standard European measurements, that's a Dan Burn and an Erling Haaland.
Linguists remain divided as to whether the correct plural of Dan Burn as a unit of measurement should properly be 'Dan Burns' or 'Dans Burn'.
Some point to 'attorneys general', 'courts martial' and 'editors-in-chief' as precedent, pointing out that the singular of the surname should be preserved as each individual Dan Burn used in the measurement would remain a Burn, but collectively they would be Dans.
Others point out that if you were inviting 2x Dan Burn to a wedding, you would refer to to them in conversation as 'the Burns'.
