What is a Megapascal and a Hectopascal?

1 MPa = 1,000,000 Pa = 1,000 kPa = 145.038 PSI = 10 bar = 9.869 atm

1 hPa = 100 Pa = 0.1 kPa = 1 mbar (exactly) = 0.001 bar = 0.0145 PSI = 0.000987 atm = 0.75 mmHg

Note: The Megapascal is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Hectopascal belongs to the imperial/US customary system.

Common Uses and Applications: megapascals vs hectopascals

Explore the typical applications for both Megapascal (imperial/US) and Hectopascal (imperial/US) to understand their common contexts.

Common Uses for megapascals

Materials Engineering: Tensile strength, compressive strength, yield strength. Hydraulics: High-pressure hydraulic systems (construction, manufacturing). Pressure Vessels: Gas cylinders, boilers, reactors. Geotechnical: Soil bearing capacity, rock strength.

When to Use hectopascals

Meteorology: Weather forecasts, atmospheric pressure reporting (worldwide standard). Aviation: Altimeter settings, flight level pressure (ICAO standard). Oceanography: Atmospheric pressure corrections for sea level measurements. Climatology: Historical pressure data, pressure trends.

Additional Unit Information

About Megapascal (MPa)

How do I convert MPa to PSI?

Formula: PSI = MPa × 145.038

Examples:

  • 1 MPa = 145 PSI
  • 10 MPa = 1,450 PSI (car brakes)
  • 20 MPa = 2,900 PSI (hydraulic tools)
  • 30 MPa = 4,350 PSI (scuba tank)
  • 70 MPa = 10,153 PSI (H2 fuel tank)

What is concrete strength in MPa?

Residential concrete: 20-32 MPa (2,900-4,650 PSI)

  • Footings/slabs: 20-25 MPa
  • Foundation walls: 25-30 MPa
  • Driveway: 25-32 MPa

Commercial concrete: 30-50 MPa

  • Floors: 30-35 MPa
  • Beams/columns: 35-50 MPa

High-strength: 50-100+ MPa

  • High-rise buildings: 50-80 MPa
  • Bridges: 60-100 MPa
  • Special applications: 100-150 MPa

Conversion: Divide PSI by 145 to get MPa (e.g., 3,000 PSI ≈ 21 MPa)

How do I convert MPa to bar?

Formula: bar = MPa × 10

Examples:

  • 0.1 MPa = 1 bar
  • 1 MPa = 10 bar
  • 2 MPa = 20 bar
  • 10 MPa = 100 bar
  • 20 MPa = 200 bar (scuba tank)

What is a typical hydraulic system pressure?

Low pressure: 7-14 MPa (1,000-2,000 PSI)

  • Automotive power steering: 8-12 MPa
  • Light hydraulic lifts: 7-10 MPa

Medium pressure: 14-21 MPa (2,000-3,000 PSI)

  • Construction equipment: 20-25 MPa
  • Agricultural machinery: 14-20 MPa
  • Automotive brakes: 10-15 MPa

High pressure: 21-35 MPa (3,000-5,000 PSI)

  • Industrial presses: 25-35 MPa
  • Heavy construction: 30-35 MPa
  • Excavators: 30-35 MPa

Very high pressure: >35 MPa (>5,000 PSI)

  • Hydraulic jacks: 50-70 MPa
  • Specialized industrial: 70-100 MPa

Why use MPa instead of PSI for material strength?

SI standard: International engineering uses MPa universally Simpler numbers: 400 MPa vs 58,000 PSI Scientific: Consistent with stress calculations (force/area in N/m²) Global: Specifications understood worldwide

Conversion: PSI ÷ 145 ≈ MPa (or PSI × 0.00689 = MPa)

Example: Steel yield strength

  • As MPa: 250-400 MPa (easy)
  • As PSI: 36,000-58,000 PSI (unwieldy)

About Hectopascal (hPa)

How do I convert hPa to PSI?

Formula: PSI = hPa × 0.0145

Examples:

  • 1,013 hPa = 14.7 PSI (sea level)
  • 1,000 hPa = 14.5 PSI
  • 900 hPa = 13.05 PSI
  • 800 hPa = 11.6 PSI

hPa to PSI converter →

Is hPa the same as mbar?

Yes, exactly! 1 hPa = 1 mbar

Why two names?:

  • Millibar (mbar): Traditional meteorology unit (1900s-1980s)
  • Hectopascal (hPa): SI-compliant name (1980s-present)
  • Same value, just renamed for SI consistency

Conversion: None needed! They're identical.

Modern usage: Weather services worldwide now use hPa, but many pilots and mariners still say "millibar."

What is normal atmospheric pressure in hPa?

Standard sea level: 1,013.25 hPa (exactly, by definition)

Typical range: 980-1,050 hPa depending on weather

Pressure variations:

  • Fair weather (high): 1,020-1,040 hPa
  • Normal range: 1,000-1,020 hPa
  • Stormy (low): 980-1,000 hPa
  • Hurricane: <980 hPa

Regional/seasonal: Varies ±30 hPa from standard

How does pressure change with altitude?

Rough approximation: Pressure decreases ~12 hPa per 100m near sea level

More accurate (ISA model):

| Altitude | Pressure (hPa) | % of Sea Level | |----------|---------------|----------------| | 0m | 1,013 | 100% | | 500m | 955 | 94% | | 1,000m | 899 | 89% | | 2,000m | 795 | 78% | | 3,000m | 701 | 69% | | 5,000m | 540 | 53% | | 8,848m (Everest) | 313 | 31% |

Formula (approximate): P = 1013 × (1 - altitude/44,300)^5.255

What hPa is considered high or low pressure?

High pressure (anticyclone):

  • Strong high: >1,030 hPa (stable, clear weather)
  • Moderate high: 1,020-1,030 hPa (fair weather)

Normal pressure: 1,005-1,020 hPa

Low pressure (cyclone):

  • Moderate low: 990-1,005 hPa (cloudy, possible rain)
  • Strong low: 970-990 hPa (rain, wind)
  • Very low: <970 hPa (storms, gales)

Extreme low: <920 hPa (major hurricanes/typhoons)

Context: Depends on region and season. 1,000 hPa may be "low" in winter anticyclone, "high" in tropical region.
