About Slugs per hour

The slug per hour (slug/h) equals 14.5939029372/3600 ≈ 4.054×10⁻³ kg/s, used in aviation aerodynamics problems expressed in foot-pound-second units. Engine mass-flow data from legacy US military specifications and NASA test reports use slug/h as an intermediate unit between the tiny slug/s and large slug/day. 1 slug/h ≈ 4.054×10⁻³ kg/s ≈ 32.174 lb/h.

About Grains per second

The grain per second (gr/s) equals 64.79891 mg/s or 6.479891×10⁻⁵ kg/s. The grain (= 1/7000 lb exactly) is the smallest avoirdupois mass unit, still used in ballistics for bullet and propellant-charge weights. A .308 Winchester rifle bullet of 168 gr fired in 1 s represents 168 gr/s; powder charge is typically 40-46 gr. 1 gr/s = 6.479891×10⁻⁵ kg/s = 64.79891 mg/s.
