When are letters numbers?


Generally in any base base 10. Base 36 for instance uses the digits 0
to Z - so every letter of the alphabet is a number.

Hex is very common (0-F), but we do have one system that uses base 36.
Base 64 encoding is also common (in which case 'a' is a different number
to 'A')


In the base that Canada uses for aircraft registration, when are letters
numbers?

That wasn't the question you asked.

All of them, as previously explained.

(As an aside to all the pedantry that's bouncing around this thread, I
think you must realise that 'numbers' is just an American figure of
speech; after all, in the US plane registrations are colloquially known
as 'N numbers', even though quite frequently the last one or two digits
is a letter, and is probably not intended to be base 36! In most other
countries, we just colloquially know our registrations as 'G-reg' or
'D-reg' or.. etc. without even mentioning the word 'numbers'. In this
part of the world, car registration plates are colloquially known as 'number
plates' even though they don't just have numbers, well, unless you live
in Guernsey).

Previous "explanations" were out of context.

In what part of America is 'numbers' just an American figure of speech? US
plane registrations are colloquially known as 'N numbers' because they are
predominantly numbers. Many are exclusively numbers.
