Convert kilopascals to megapascals using the exact SI relation 1 MPa = 1,000 kPa. Anchors: 100 kPa = 0.1 MPa, 1,000 kPa = 1 MPa, 25,000 kPa = 25 MPa (hydraulic), 100,000 kPa = 100 MPa (concrete strength). Useful when low-precision metric pressures need to be reported in the MPa scale used for engineering data sheets. Browser-local.

Glossary

Kilopascal (kPa)

A kilopascal equals 1,000 pascals. It is the everyday metric pressure unit for tire pressure outside the US (32 psi ≈ 220 kPa), atmospheric pressure (~101 kPa at sea level), HVAC duct pressure and blood-pressure readings reported in metric form (120/80 mmHg ≈ 16.0/10.7 kPa). The standard atmosphere equals 101.325 kPa exactly.

Megapascal (MPa)

A megapascal equals 1,000,000 pascals or 10 bar. It is the standard engineering unit for hydraulic systems, high-pressure gas, water-jet cutting, material yield strength and concrete compressive strength. Typical hydraulic systems run at 10–35 MPa; structural concrete reaches 20–80 MPa; high-pressure water jets exceed 400 MPa.

Metric / SI pressure

In the metric system, pressure is reported in pascals (SI base) or its multiples — kilopascal (kPa, 10³ Pa), megapascal (MPa, 10⁶ Pa) — and the related non-SI unit bar (10⁵ Pa). The millibar/hectopascal (mbar = hPa = 100 Pa) is used in meteorology. All metric units relate by exact powers of ten, so conversions between them are simple shifts of decimal point.

Imperial / US pressure

US engineering and automotive primarily report pressure in pounds per square inch (psi). 1 psi ≈ 6,894.76 Pa, defined as one pound-force per square inch. Standard atmospheric pressure is 14.696 psi. The closely related "psi-gauge" (psi-g) measures pressure above atmospheric, while "psi-absolute" (psi-a) measures total pressure including atmospheric.
