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!
