Question

How can I measure gas pressure?

Answer 1

There are many techniques to measure gas pressure.

For example, an instrument called the manometer uses a column of liquid to measure gas pressure.

Some units that are used to measure gas pressure are: pascal, torr, bar, and psi (pounds per square inch). But the SI unit for pressure is the pascal (Pa), which is equal to one newton per square meter (N/m²).
