About Slugs per second
The slug per second (slug/s) equals 14.5939029372 kg/s, derived from the Imperial system where 1 slug = 1 lb·s²/ft ≈ 14.594 kg. The slug is the coherent mass unit in the foot-pound-second system; rocket propulsion engineers using US customary units express mass flow in slug/s. A standard American rocket engine consuming 75 000 lb/s of propellant corresponds to ≈75 000/32.174 ≈ 1 830 slug/s. 1 slug/s = 14.5939029372... kg/s.
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.
