The sciatic nerve is the longest and thickest nerve in the human body, measuring just under 1 inch (2.54 cm) in width, comparative to the diameter of a finger. It runs from the lower spine through the pelvic area and down through the hip and back of the leg.he sciatic nerve is the longest and thickest nerve in the human body, measuring just under 1 inch (2.54 cm) in width, comparative to the diameter of a finger.

How many Bars in a Psi. 1 Psi is equal to 0.06894757293168 Bar. The bar is a metric unit of pressure equal to 100000 Pascal (Pa). The bar is also equal to 1x105 N/m2. Psi is known as pound-force per square inch.
Work in one unit system. 100 psi = 689.476 kPa. Pressure = force/area, so multiply by the area over which the pressure acts to get the force. If pressure is in pascals, and area in square meters, force will be in newtons.
