Generally speaking, when you convert a number expressed using a smaller unit into a number expressed using a larger unit the number will get smaller (see examples A & B).

Also, when you convert a number expressed using a larger unit into a number expressed using a smaller unit the number will get bigger (see example C).

One last note: recognize the value of the prefixes when dealing with numbers like those in examples A & B. Who wants to write all those zeros when you can assume they are there just by knowing how small/large the prefix makes the base unit?
