What is the unit of pressure in SI units? (2023)

Step 1: Understand that pressure is a measure of force applied over an area.
Step 2: Know that the SI unit system is a standard system of measurement used worldwide.
Step 3: Learn that the unit of force in SI units is Newton (N).
Step 4: Recognize that area is measured in square meters (m²) in SI units.
Step 5: Combine these two units to define pressure: Pressure = Force / Area.
Step 6: Therefore, the unit of pressure is Newton per square meter, which is written as N/m².
Step 7: The Pascal (Pa) is defined as 1 N/m², so the SI unit of pressure is Pascal (Pa).
