Megapascals (MPa) to Kilopascals (kPa) Conversion
Megapascals
The megapascal (MPa) is a unit of pressure equal to exactly 1,000,000 pascals (10⁶ Pa) and is the standard unit for expressing material strength, hydraulic system pressure, and structural loading in engineering. The tensile strength of structural steel is approximately 400–600 MPa; high-strength carbon fibre composites can exceed 3,500 MPa. Hydraulic systems in heavy machinery operate at 20–70 MPa. In geology, lithostatic pressure in the Earth's crust is measured in MPa and GPa.
Kilopascals
The kilopascal (kPa) is a unit of pressure equal to exactly 1,000 pascals and is one of the most practical pressure units for everyday engineering. Standard atmospheric pressure is approximately 101.3 kPa. Tyre pressure is commonly specified in kPa in metric countries: a typical car tyre is inflated to 220–250 kPa. Blood pressure in clinical settings is measured in mmHg, but some medical devices express it in kPa (normal systolic ≈ 16 kPa).
