What is Millimeter of mercury?

The millimeter of mercury is a unit of pressure based on the height of a mercury column, equal to approximately 133.3 pascals. It is the universal standard for reporting blood pressure in medicine: normal blood pressure is below 120 mmHg systolic and 80 mmHg diastolic. The unit originates from Torricelli's 1643 experiment, which showed that atmospheric pressure supports a mercury column of about 760 mm. One mmHg is nearly identical to one torr.

What is Megapascal?

The megapascal equals one million pascals and is widely used in materials and structural engineering. Concrete compressive strength typically ranges from 21 to 35 MPa, and steel tensile strength ranges from about 400 to 800 MPa. Hydraulic equipment operates at pressures of tens of megapascals. The unit is essential for specifying material properties, bolt preloads, and pressure vessel ratings in industrial applications.
