Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different.
The California king size is a mattress measuring 72 inches wide by 84 inches long. In terms of length it is four inches longer than the standard king and queen size mattresses. The mattress was made by David Bergeson of California sometime in 1982.
The same technology is used to make longer 8-in and 12-in calipers; the accuracy for bigger measurements declines to 0.001 in (0.03 mm) for 100â200 mm and 0.0015 in (0.04 mm) for 200â300 mm. Many digital calipers are inexpensive and perform reasonably well.
