Formula: Megapascal = Pascal × 1.0000e-6
Multiply any pascal value by 1.0000e-6 to get megapascal.
Reverse: Pascal = Megapascal × 1e+06

The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter. It was named after Blaise Pascal, the 17th-century French mathematician and physicist who studied fluid pressure. The unit was officially adopted by the International System of Units in 1971.
Pascals are used in meteorology (atmospheric pressure ~101,325 Pa), materials science (Young's modulus in GPa), and fluid mechanics. The pascal is very small — standard atmospheric pressure equals 101,325 Pa.
Interesting fact: Blaise Pascal demonstrated in 1648 that atmospheric pressure decreases with altitude by carrying a barometer up the Puy de Dôme mountain, confirming Torricelli's theory of atmospheric pressure.
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 pascal 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 Pa = 5.0000e-6 MPa and 10 Pa = 1.0000e-5 MPa. For the reverse: 1 MPa = 1e+06 Pa. The exact factor is 1 Pa = 1.0000e-6 MPa.
All conversions use IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
