Question #da813 Physics Introduction to Physics Measurement and Units 1 Answer GiĆ³ Apr 5, 2017 I tried this: Explanation: Pressure is Force over Surface or #N/m^2# (Newton divided by meter squared). Multiply top and bottom by #m#: #(Nm)/m^3# But #Nm=J# Joule as in Work or Energy; #m^3# is Volume; so #"Pressure"=J/m^3# energy per volume or energy density.
