What is a conversion factor?
In Science and Mathematics, a conversion factor is a number that is used to convert a number in one set of units to another, either by dividing or multiplying.
In order to determine the number of kilos that Pedro packaged in total, we would have to convert the eighths of a kilo into kilos. Since there are 8 eighths in a whole kilo, the number of eighths should be divided by 8 as follows;
Total kilos = 72/8
Total kilos = 9 kilos.
