Or, you can find the single factor you need by dividing the A factor by the B factor.įor example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into Pascals then divide by the factor for B to convert out of Pascals. Typically, the unit mmHg is utilized to estimate the pressure and its. To convert from Pa into units in the left columnĭivide by the value in the right column or, multiply by the reciprocal, 1/x.ĥ00000 Pa / 100000 = 5 bar Various units of pressure can be found in science like mmHg, atm, bar, and many more. Multiply by the conversion value in the right column in the table below.ĥ bar * 100000 = 500000 Pa To simply convert from any unit into pascals, for example, from 5 bar, just We review their content and use your feedback to keep the quality high.

How to Convert Units of PressureĬonversions are performed by using a conversion factor. By knowing the conversion factor, converting between units can become a simple multiplication problem: Some are obvious, such as pounds per square inch, but even the SI standard Pascal is actually an expression of one Newton per square meter. This formula is called the ideal gas law. Since pressure is derived from force and area, many units for pressure directly relate force to area. The unit of pressure used to be torr, also known as mmHG (millimeter mercury).

Where P is equal to pressure, F is the normal force and A is area.

Pressure is a scalar quality reflecting how force acts on a surface.
