Pressure Converter — Pa, kPa, bar, atm, psi & Torr

Easiest Converter’s pressure converter gives clean, reliable results across engineering, HVAC, automotive, laboratory, beverage/food processing, and weather applications. Convert between pascal (Pa), kilopascal (kPa), bar, atmosphere (atm), pound per square inch (psi), and Torr (mmHg) with fast, readable output you can copy or share.

Calculations are referenced to the pascal for consistent math across metric and imperial systems. Popular pairs include kPa ⇄ psi for tires and hydraulic specs, bar ⇄ psi for pumps and compressors, and atm ⇄ kPa for scientific contexts. For vacuum and lab work, use Torr (mmHg) to match common gauges and protocols.

Why use this pressure converter? The interface is tuned for clarity and accessibility—keyboard-friendly inputs, a one-tap swap button, subtle high-contrast design, and copy-to-clipboard results. Numbers are formatted for sensible precision, keeping decimals tidy while preserving accuracy for worksheets, reports, and field notes.

Supported units: Pa, kPa, bar, atm, psi, Torr (mmHg). Whether you’re calibrating equipment, checking tire pressures, documenting experiments, or interpreting datasheets, this tool keeps your conversions fast, consistent, and easy to read.

• Use ⇄ to swap “From” and “To” in one tap.
