How many 5p's in 1 mile?

Answer 1

Depending upon which way you lay the coins:

a 5p has a thickness of 1.7mm and a diameter of 18.0mm

1 mile = 1,609,344 mm (exactly)

→ if the coins are laid on heads/tails it will require 1,609,344 mm ÷ 18.0 mm/coin = 89,408 coins

→ if the coins are laid on edge it will require 1,609,344 mm ÷ 1.7 mm/coin = 946,672 16/17 coins ≈ 946,672.9 coins; 946,673 coins laid on their edge will be 0.1mm longer than 1 mile.

Answer 2

In 1990 a new smaller version was introduced with a diameter of 18.00 mm. Therefore, how many 18 mm goes into 1 mile. 1,609,340mm ÷ 18mm = 89,407.777777778
Or 89,408 coins approximately.
