Joker - I just e-mailed a fantastic conversion program to you. It is a .exe file. Just select your input (cubic inches - 235) and your output (liter) and you get your answer (3.85096).
This program will convert almost anything, volume, distance, area, torque, desity, force, etc.
Have fun and amuse your friends.

Gravity - It's not just a good idea, it's the law.
