How can i remember the English System and SI easily in Chemistry?

Question

 I really need help with this.

Answer 1

I suggest you practice a wide variety of problems, half of them worked in SI units and half of them worked in English units.  Working out problems in the different systems helps you retain them.  

Answer 2

1.  make flash cards

2.  review them repeatedly, multiple times per day(even saying them aloud) until the're fixed in your memory.
