تحويل الجنيه إلى الحبة: إعادة تحميل الذخيرة والصيدلة والمعادن الثمينة

Exactly 7,000 grains equal one pound avoirdupois. This is a defined relationship maintained internationally. One grain equals 64.79891 milligrams or 0.06479891 grams. For ammunition reloading and pharmaceutical work, this precise conversion is critical—use 7,000 grains per pound for all calculations without rounding.

Grain measurements provide the precision needed for ballistic consistency. A single grain difference in powder charge can alter bullet velocity by 15-20 feet per second, affecting accuracy at distance. Reloading manuals, powder manufacturers, and ballistic data have been published in grains for over a century. Additionally, traditional reloading scales are calibrated in grains, making this system deeply embedded in the reloading community's infrastructure and expertise.
