Pressure conversion
Pressure is defined as the force per unit area and can be represented using various standards:
- Pascal (Pa) is the SI unit for pressure.
- Bar is widely used in industrial applications.
- Psi (pounds per square inch) is common in the US and UK.
- mmH₂O or mmWC (water column) is often used for low pressure ranges, such as in ventilation systems.
Our conversion tables allow you to quickly switch between units and avoid confusion when working with international specifications.
