... His discovery of what he called the megalithic yard (2.72 feet, or 0.83 metres), a unit of measurement he found employed consistently at many prehistoric megalithic sites, is a key feature of his book Megalithic Sites in Britain, published in 1967, for which he had surveyed some 300 megalithic circles, alignments, and isolated standing stones.

The Megalithic yard equals 1/2 square root of 3 times Pi or 0.8660254 times 3.14159 = 2.7207

BUT MORE IMPORTANTLY ....

The megalithic yard also equals 1/1,000,000 th of the circumference of The Sun in a ratio of yards to miles ...
