Look up conversion factors for grams -> pounds,
and liters or milliliters -> cu ft. Use dimensional analysis to cascade them and cancel units
0.916 g /ml x 1 lb/453.59237 g x 28316.8466 mL/1 cu ft =
57.18 lb/cu ft.
My conversion factor was actually liters per cubic foot. I just moved the decimal 3 places to get milliliters.
