Frequently Asked Questions
What is the difference between absolute and gauge pressure?
Absolute pressure is measured relative to a perfect vacuum, while gauge pressure is measured relative to atmospheric pressure. Most pressure units can represent both types depending on the reference point.
How accurate are the pressure conversions?
Our conversions use precise conversion factors and display results in scientific notation for maximum accuracy. The calculations are suitable for engineering and scientific applications.
What is the most commonly used pressure unit?
Pascal (Pa) is the SI base unit for pressure, but Bar and PSI are commonly used in engineering applications. Atmospheric pressure is often used in meteorology.
Can I convert vacuum pressure measurements?
Yes, the conversion factors work for both positive and negative pressure values, including vacuum measurements below atmospheric pressure.
