The grain is one of the oldest units of weight, originally based on the weight of a single grain of barley. One grain equals exactly 64.79891 milligrams or approximately 0.0648 grams. Despite its ancient origins, the grain remains widely used today, particularly in the ammunition industry for measuring bullet and gunpowder weights. It's also used in the troy weight system for precious metals, where 480 grains equal one troy ounce. The grain is identical across the avoirdupois, troy, and apothecaries' systems, making it a universal small-weight standard in both imperial and troy measurements.
One grain equals exactly 0.06479891 grams or approximately 64.8 milligrams.
Grains have been the traditional unit for ammunition weight for centuries. The system provides precise measurements for small projectiles and is universally understood in the firearms industry.
A 115-grain 9mm bullet weighs approximately 7.45 grams. A 147-grain bullet weighs about 9.53 grams. Most handgun bullets range from 5-15 grams.
One gram equals approximately 15.4324 grains. This is calculated by dividing 1 by 0.06479891.
Yes, the grain is the only unit that is identical across the avoirdupois, troy, and apothecaries' weight systems, always equaling exactly 64.79891 milligrams.
One troy ounce equals exactly 480 grains. This relationship is fundamental to the troy weight system used for precious metals.
