Algodoo

This scene shows how to scale Algodoo for imperial units by setting gravity to 1.0. Force, mass, and distance in N, kg, and m are replaced by force, mass, and distance in pounds force, pounds mass, and inches. Time slows down by a factor of 19.65 which can be counteracted by increasing the simulation speed to 19.65 to have the scene run in real time speed (although time and velocity values will still be off by a factor of 19.65 and 1/19.65 respectively).
