You can put this solution on YOUR website! What is the volume of 1.0 liter expressed in mm3?
----------------
Start with 1 liter = 1000 cc (cubic centimeters)
1 cm = 10 mm
--> 1000 *10*10*10
= 1,000,000 mm^3
---------------
or, 1*10^6 mm^3
or, 1E6 mm^3
----------------
It's a lot of zeroes, but it's better than multiplying by 1728.
