Grains per second (gr/s)

Conversion Formula

gr/s = g/min × 0.2572059725

About Grams per minute

The gram per minute (g/min) equals 10⁻³/60 ≈ 1.667×10⁻⁵ kg/s, common in food processing (condiment dispensing, coffee brewing), and laboratory flow chemistry. A standard espresso machine draws water at ≈30 g/min through the portafilter; a micro-reactor feed pump for organic synthesis is calibrated in g/min. 1 g/min = 1/60 g/s ≈ 1.667×10⁻⁵ 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.
