Pressure Unit Conversion Guide for Science and Industry

2026-04-04

Accurate pressure measurement is critical in scientific research and industrial applications, yet the variety of units used across different fields and equipment can create confusion. A minor conversion error may lead to experimental failures or even safety hazards. Mastering pressure unit conversions is therefore an indispensable skill for researchers and engineers.

Comprehensive Pressure Unit Conversion Guide

This reference provides detailed conversion relationships between seven commonly used pressure units:

MPa (Megapascal): The standard SI unit for high-pressure systems. 1 MPa equals 1,000,000 Pa.
bar: Widely used in meteorology and industry, approximately equal to atmospheric pressure. 1 bar equals 100,000 Pa.
kgf/cm² (Kilogram-force per square centimeter): Common in engineering, representing force per unit area. 1 kgf/cm² equals 98,067 Pa.
kPa (Kilopascal): A standard SI unit equal to 1,000 Pa.
mmHg (Millimeters of mercury): Used in medicine and meteorology, based on mercury column height. 1 mmHg equals 133.32 Pa.
hPa (Hectopascal): Common in meteorology, equal to 100 Pa.
Pa (Pascal): The fundamental SI unit of pressure (1 N/m²).
