Prince William and Kate Middleton could have had 9632 wedding ceremonies in Westminster Abbey (they sent out 1,900 invites)
The amount of viewers would fill 732,000 London Eye pods
Wembley Stadium could be filled 203 times
It would take 32,973 Airbus A380 planes (that’s the world’s largest passenger airplane) to transport them across the Atlantic
It makes up just under the combined number of inhabitants in Scandinavia (Norway, Denmark and Sweden)
