🧱 MPa Conversion
Translate MPa values into kPa, bar, atm, psi, psig, mbar, and mmHg.
Megapascals are common in structural engineering and hydraulics. This tool lets you express the same pressure in units more familiar to technicians, vendors, and international partners.
Kilopascals (kPa)1,000

Formula
kPa = MPa × 1,000
bar = MPa × 10
atm ≈ MPa × 9.86923
psi ≈ MPa × 145.038
mmHg ≈ MPa × 7,500.62
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Megapascals simplify calculations for high-pressure systems, but suppliers and technicians often request psi or bar. This converter keeps everyone aligned by providing accurate equivalents instantly.
Gauge pressure (psig) is included for compressor and piping contexts where readings exclude atmospheric pressure by default.
Frequently Asked Questions
What is the difference between psi and psig?
psi measures absolute pressure, while psig measures pressure relative to atmospheric pressure (psig = psi − 14.6959).
Can I convert MPa to Pa?
Multiply MPa by 1,000,000 to get Pascals. Use the measurement converter or extend this page if needed.
Does temperature affect the conversion?
The unit conversions are independent of temperature. Only fluid properties or gauge readings may change with temperature.
Why include mmHg?
Some vacuum and medical equipment still reference mmHg, so it helps bridge those contexts.
