Millimeter Of Mercury (abbreviations: mm Hg, or mmHg): is a manometric unit of pressure, equal to 133.322387415 pascals. It is the extra pressure generated by a column of mercury of one millimeter high.
Pascal (abbreviations: Pa, or N/m2): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one newton per square meter. It is named after the French polymath Blaise Pascal.
How to Convert Millimeters Of Mercury to Pascals
Example: How many pascals are equivalent to 90.81 Millimeters of Mercury?
As;
1 Millimeters of Mercury = 133.322387415 pascals
90.81 Millimeters of Mercury = Y pascals
Assuming Y is the answer, and by criss-cross principle;
Y equals 90.81 times 133.322387415 over 1
(i.e.) Y = 90.81 * 133.322387415 / 1 = 12107.006001156 pascals
Answer is: 12107.006001156 pascals are equivalent to 90.81 Millimeters of Mercury.
