Answer:
Compare your two units. The two units must measure the same thing.
For example, in the problem "convert 2 inches into centimeters," both inches and centimeters measure length. If your units measure two different things (like length and weight), you can't convert between them.

Look up the conversion. Before you can do the math, you need to know how much larger one unit is than the other.If the conversion you find has many decimal places, round to the nearest significant digit. If you don't know what a significant digit is, round to the second or third digit.
