6. Another Example 1) Write the number (with units) that you want to convert. 2) Multiply it by a conversion factor, written as a fraction. Make sure the unit that you want to convert from is on the bottom and the unit you want to convert to is on the top. 3) Make sure the old units cancel. 4) Multiply all of the numbers on the top and divide by all of the numbers on the bottom to find your answer. Convert 52.8 hours to days. 52.8 hrs 52.8 hrs X 1 day 24 hrs 52.8 hrs X 1 day 24 hrs 52.8 hrs X 1 day 24 hrs = 2.2 days
