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.
Since the measurement is in the metric system, 1,000 millibars equal one bar. A bar is a force of 100,000 Newtons acting on a square meter, which is too large of a unit to be a convenient measure of Earth's air pressure. Inches of mercury and centimeters of mercury measure how high the pressure pushes the mercury in a barometer. (Related: Calculate pressure conversions).
