Assuming you are talking about stoichiometery a conversion factor is often a number with two units. For example a conversion factor could be Miles per hour (Miles/hour). If you had miles and needed to convert to hours you would multiply the miles by Hours/miles so that the miles would be canceled out (miles/miles = 1). Then your units left would be hours. Or vice versa. There are other factors like this in chemistry like grams/mol Mol/liter etc. To put it shortly the conversion factor denominator is always paired with the numerator.
Multiply Km by 10^6
365 days in a non-leap year 24 hours in a day 60 minutes in an hour 60 seconds in a minute 365 x 24 x 60 x 60 = 31,536,000 seconds in a year. Divide 1 by 31,536,000 gives 1 second is .00000003170979 years
The conversion factor is 1,000 (km x 1,000 = meters)
To convert Kg to grams, divide by 10. This will give the grams as needed. To convert grams to Kg, the number should be multiplied by ten.
The first caveman who wanted to trade some buffalo meat in return for a couple of days with his neighbor's wife needed math to calculate the optimum meat conversion factor.
