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.
About Micrograms per minute
The microgram per minute (µg/min) equals 10⁻⁹/60 ≈ 1.667×10⁻¹¹ kg/s, used in capillary electrophoresis and gas chromatography mass flow calibration. A typical cold-trap atmospheric sampler collecting particulate matter draws air at a rate characterized in µg/min of PM2.5. 1 µg/min = 1/60 µg/s ≈ 1.667×10⁻¹¹ kg/s.
