WebIn SI units, force is measured in newtons and area in square metres. This means stress is newtons per square meter, or N/m 2. However, stress has its own SI unit, called the pascal. 1 pascal (symbol Pa) is equal to 1 N/m 2. In Imperial units, stress is measured in pound-force per square inch, which is often shortened to Web12 mag 2012 · I have a dispersion relation that involves some constants (and it's in natural units so no c or hbar shows up). I'd like to plot E versus k using this equation with k and E in SI units. There are some terms with k^2/(2m) so I can just multiply those by hbar^2, but then there's another term that is only linear in k which I don't know what to do ...
