Formula
Pa ≈ psi × 6,894.757
kPa = Pa ÷ 1,000
bar ≈ psi ÷ 14.5038
inH₂O ≈ psi × 27.7076
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
psi is widespread in North America, but cross-functional teams often need bar, kPa, or gauge values. This converter handles all major units without manual work, ensuring consistent communication.
Gauge pressure (psig) and column units like inH₂O and inHg make it easy to interface with HVAC and process control equipment.
Frequently Asked Questions
What is the difference between psi and psig?
psi is absolute pressure; psig subtracts atmospheric pressure (≈14.6959 psi).
Can I convert psi to Pa manually?
Multiply psi by 6,894.757 to obtain Pascals.
Does altitude affect conversions?
Only gauge conversions (psig) depend on local atmospheric pressure. Absolute conversions are fixed.
How precise are the results?
Each unit uses the precision defined in the shared pressure utilities for engineering accuracy.
