Pressure Converter

About This Tool

This Pressure Converter is an essential tool for engineers, scientists, meteorologists, and anyone working with fluid dynamics or mechanical systems. Pressure is defined as the force applied perpendicular to the surface of an object per unit area over which that force is distributed. The base unit for all calculations is the pascal (Pa), which is the standard SI unit of pressure.

The tool covers a wide range of units, from the pascals used in scientific research to the pounds per square inch (psi) common in industrial applications and the atmospheres (atm) or millibars (mbar) used in weather forecasting. It allows for seamless conversion between metric and imperial/customary systems, ensuring you can find the exact value you need for your calculations.

Tips & Features

• The Pascal Standard: All pressure units are converted by first relating their value back to the pascal (Pa), which is equivalent to one newton of force per square meter (N/m²). This ensures maximum accuracy.
• Atmospheric vs. Technical Atmospheres: This converter includes both the 'standard atmosphere' (atm), which is based on the average atmospheric pressure at sea level, and the 'technical atmosphere' (at), which is defined as one kilogram-force per square centimeter. Be sure to select the correct one for your application.
• Gauge vs. Absolute Pressure: This tool converts pressure values, but it's important to know if your measurement is 'gauge pressure' (relative to ambient atmospheric pressure) or 'absolute pressure' (relative to a perfect vacuum). The conversion between units remains the same, but the context of the measurement is key.
