# Absolute, Gauge, Bidirectional, Differential, Vacuum, and Barometric Pressure... What's the difference?

**Pressure can be expressed in different ways. Gauge pressure is the pressure above or below the current atmospheric pressure and absolute is the pressure above absolute zero. View the  video describing all the variations graphically.**

Key points addressed:

- What is gauge pressure?
