Conversion from kilo grain feet per second to newton-seconds is trivial, since both the grain and foot is based on SI units. One troy grain is defined as 0.064 798 91 grams exactly [1] and one international foot is defined as 0.3048 meters, giving the exact conversion factor of 0.019 750 707 768. [2]
