Multiply any torr value by 0.0001333 to get megapascal.
Reverse: Torr = Megapascal × 7501

Multiply result by 7501 to recover the original Torr value.
Specifies concrete compressive strength (20–50 MPa) and steel yield strength (250–550 MPa).

Specifies wellbore pressure, reservoir pressure, and fracture gradients in MPa.
Sets cutting pressure (200–600 MPa) for precision cutting applications.
The torr was named after Evangelista Torricelli, who invented the mercury barometer in 1644. One torr is defined as 1/760 of standard atmospheric pressure (133.322 Pa), and is equal to 1 mmHg at 0°C.
Torr is the standard pressure unit in vacuum science and semiconductor manufacturing. High vacuum systems operate at 10⁻³ to 10⁻⁷ torr. Ultra-high vacuum (used in particle accelerators) reaches below 10⁻¹⁰ torr.
Interesting fact: Torricelli's original barometer experiment used a 1-meter tube of mercury that settled at 760 mm above the reservoir — directly defining the unit that would later bear his name.
The megapascal (MPa) equals 1,000,000 pascals (1,000 kPa) and is the standard unit for high-pressure engineering applications including hydraulics, structural materials, and industrial processes.
Steel has a tensile strength of about 400–550 MPa; concrete compressive strength is typically 20–40 MPa. Hydraulic systems in heavy machinery operate at 20–35 MPa. Water jet cutting uses pressures up to 600 MPa.
Interesting fact: The deepest point in the ocean (Mariana Trench, ~11,000 m) has a pressure of about 110 MPa — over 1,000 times atmospheric pressure.
Converting torr to megapascal is a common task in engineering, medicine, meteorology, and science. Different industries and countries use different pressure units — PSI in the US, bar in Europe, mmHg in medicine, and pascals in physics — making accurate conversion essential for cross-disciplinary work.
Quick reference: 5 Torr = 0.0006666 MPa and 10 Torr = 0.001333 MPa. For the reverse: 1 MPa = 7501 Torr. The exact factor is 1 Torr = 0.0001333 MPa.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
