Questions & Step-by-Step Solutions

What is the relationship between the units of pressure in SI? (2019)
  • Step 1: Understand what pressure is. Pressure is the force applied over a certain area.
  • Step 2: Know the unit of force in SI, which is the Newton (N).
  • Step 3: Know the unit of area in SI, which is square meters (m²).
  • Step 4: Learn the definition of 1 Pascal (Pa). It is defined as 1 Newton of force applied over an area of 1 square meter.
  • Step 5: Therefore, 1 Pa = 1 N/m², meaning that pressure in Pascals is the same as Newtons per square meter.
