How to Use This Calculator
Enter pressure
Type the value you have from instrumentation or calculations.
Choose original unit
Select the unit that matches the input (Pa, bar, psi, etc.).
Review conversions
Copy the equivalent value in whichever target unit you need.
Formula
Conversions rely on SI Pascals as the base unit.
Example: bar = Pa ÷ 100,000
Example: psi ≈ Pa ÷ 6,894.757
Example: inH₂O ≈ Pa ÷ 249.08891
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Pressure measurements appear in many formats depending on the industry. This tool keeps your discussions consistent by showing every major unit at once, eliminating manual conversions or spreadsheet lookups.
Because it’s powered by the shared pressure utilities, the outputs stay synchronized with other calculators in the application.
Frequently Asked Questions
