How to Use the Weight Conversion Table
To convert from one weight to another using the above table, find the weight you are converting from in the left-most column.
Next, find the column heading you want to convert to, and take note of the factor that's in the same row.
Finally, simply multiply the number of "From" units by the factor where the two weights intersect.
To illustrate, if you want to convert from 10 carats to grams, you would find the "carats" row in the left-most column and note the factor listed on the same row in the "grams" column. There you will see that 1 carat is equal to 0.2 grams. Finally, multiplying 10 (carats) by 0.2 (grams) tells you that 10 carats is equivalent to 2 grams.
