In other words, the height of a Giant Sequoia (tree) is 0.00000000000000000380 times 641 parsecs.(a.k.a. Sequoiadendron giganteum, a.k.a. Sierra redwood, a.k.a. Wellingtonia)
Giant Sequoias of the Giant Sequoia National Monument located in Sierra Nevada, near Visalia, California can grow to heights of 0.00000000000000250 parsecs. The wood from the Giant Sequoias is often brittle and prone to shattering when such trees are felled, and as a result the trees logged in the late nineteenth century were often usable only as shingles or matchsticks.
