MPa Conversion Calculator — Megapascals to All Pressure Units
Convert megapascals (MPa) to and from pascal, kilopascal, gigapascal, bar, millibar, standard atmosphere, psi, ksi, Torr, and mmHg — all in one step.
From unit
1 MPa = 1,000,000 Pa = 10 bar = 145.038 psi ≈ 9.869 atm

Convert to pascals
1 × 1.000.000 = 1.000.0001 MPa = 1.000.000 Pa - 2
Convert Pa to MPa
1.000.000 ÷ 1.000.000 = 1
Wie funktioniert dieser Rechner?
1 MPa = 1,000,000 Pa = 10 bar = 1,000 kPa = 145.038 psi ≈ 9.869 atm ≈ 7,500.6 Torr. Convert by multiplying by 10⁶ Pa, then dividing by the target unit factor. MPa equals N/mm² (used in structural engineering). All values are absolute pressure — add ~0.101 MPa to convert gauge to absolute.
Formel
How this is calculated
The megapascal (MPa) is a metric unit of pressure equal to one million pascals (10⁶ Pa) or 10 bar. It is the standard unit in structural engineering (concrete strength), materials testing, hydraulics, and high-pressure industrial systems. The pascal (Pa = N/m²) is the SI base unit, making it the natural intermediate for all conversions: convert the source value to Pa, then divide by the target unit's per-pascal factor.
Key reference points: 1 MPa = 10 bar = 145.038 psi = 1,000 kPa = 0.001 GPa ≈ 9.869 atm ≈ 7,500.6 Torr/mmHg. The bar and millibar are exact metric multiples of Pa (1 bar = 100,000 Pa exactly). The psi is derived from the exact definitions of pound-force (4.448222 N) and inch (25.4 mm), giving 1 psi = 6,894.757 Pa. The standard atmosphere is defined as exactly 101,325 Pa. The Torr and mmHg are approximately equal (133.322 Pa each) — they agree for most purposes but differ in precise metrology.
All values are absolute pressure (measured from a perfect vacuum). Gauge pressure — common in hydraulics and tyre pressure — adds local atmospheric pressure (~0.101325 MPa). To convert gauge to absolute, add 0.101325 MPa.
Häufige Fragen
1 MPa = 145.038 psi (pounds per square inch). Conversely, 1 psi ≈ 0.006895 MPa. This is a common conversion in engineering: hydraulic system pressures given in MPa can be compared with imperial specifications in psi.
Yes — 1 MPa = 1 N/mm² exactly. This equivalence is widely used in structural and materials engineering: tensile strength and concrete compressive strength are often quoted interchangeably in MPa or N/mm².
Absolute pressure is measured relative to a perfect vacuum; gauge pressure is relative to local atmospheric pressure (~0.101325 MPa at sea level). To convert gauge pressure to absolute, add ~0.101325 MPa. Tyre pressures and hydraulic gauges read gauge; fluid column heights give absolute.
