In January 1939 a specification was issued for a gun no heavier than 5.5 tons to replace the 6 inch 26 cwt howitzers in use with most medium batteries. For the desired range of 16,000 yards (15 km) ballistic studies recommended making a new calibre of 5.5 inches.
The square root of 5 is the positive real number that, when multiplied by itself, gives the prime number 5. It is more precisely called the principal square root of 5, to distinguish it from the negative number with the same property. This number appears in the fractional expression for the golden ratio.

A list of articles about numbers (not about numerals). Topics include powers of ten, notable integers, prime and cardinal numbers, and the myriad system.
5.5mm scale narrow gauge model railways were developed by GEM in 1963, using 12 mm (0.472 in) gauge track, which was the smallest commercially available gauge at the time (). [1]
The smallest possible number of vertices of G is the induced Ramsey number r ind (H). Sometimes, we also consider the asymmetric version of the problem. We define r ind ( X , Y ) to be the smallest possible number of vertices of a graph G such that every coloring of the edges of G using only red or blue contains a red induced subgraph of X or ...
11 is a prime number, and a super-prime. 11 forms a twin prime with 13, [6] and sexy pair with 5 and 17. The first prime exponent that does not yield a Mersenne prime is 11. 11 is part of a pair of Brown numbers. Only three such pairs of numbers are known. [citation needed] Rows in Pascal's triangle can be seen as representation of powers of 11 ...
