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.
A barometer measures atmospheric pressure. It is measured in various units, one of the oldest being inches of mercury. Other units include pounds per square inch (PSI) kilo-Pascals (kPa) and atmospheres (ATM). Standard pressure is 29.92 inches of mercury, 14.7 PSI, 100 kPa or 1 ATM. Lower barometer readings are generally associated with less stable weather (as in, low pressure system), while higher ones are generally associated with more stable weather (as in, high pressure system).
