How do you go about learning all of the different units used in chemsirty? And how do you learn how to easily convert units?
Thank you! :)

Hey! With the units for chemistry, start by remembering the basic ones. Everything will be in g or L or mol. We never use kg, mg, mL, Mmol as the standard units in our calculations. Then work on the conversions as if they are maths questions.
e.g. to go from M (g/mol) from g/L you will need to multiply L/mol which is the reciprocal of mol/L which is the units for molar mass, so just times the M by molar mass! (this is a technique called solving the units)
You also need to memorise the scientific notations for things like mL (x10^3), nanoL, picoL etc.
Once you have that just do practice questions!
