### The units for each equation we're using?

The problems often give us the data in units where we have to convert. I have trouble keeping track which equations require which units. What are the units for each equation?

I would also really appreciate someone listing out the units. If it's possible, could whoever answers this also distinguish the units for each variable as well as the equation overall? Thank you!

Hi KNguyen_3G! I'm a little confused as to what you mean by "equation"? Which equations specifically? The Heisenberg uncertainty, Schrodinger's equation, or the DeBroglie equation? Most of them have to do with frequency with units s$^{-1}$ (or Hz), lambda (or wavelength) with units of meters, Planck's constant with units Joules$\cdot$Seconds, Rydberg's constant with units s$^{-1}$, momentum with units kg$\cdot$m$\cdot$s$^{-1}$. Note that Energy (Joules) has units kg$\cdot$m$^{2}$$\cdot$s$^{-2}$[tex].

theres a list of constants and equations on lavelle's site with units for the constants

On the class website there's a link that says Constants and Equations, that should help you :)
