What are grains?
Grains are a unit of measurement commonly used in the imperial system to measure the weight of small objects such as bullets, arrows, and jewelry.
One grain is equivalent to approximately 0.0648 grams or 0.0023 ounces and are still used in certain industries where precision is crucial, such as in the production of pharmaceuticals and supplements.
What are Troy Pounds?
A troy pound is about 373.24 grams, which makes it lighter than the avoirdupois pound of 453.59 grams. It was the pound of the precious metals trade, though gold and silver are now quoted per troy ounce.
One troy pound is equivalent to 12 troy ounces, which is lighter than the avoirdupois pound commonly used in everyday measurements. The troy pound is often denoted by the symbol "lb t" to distinguish it from the avoirdupois pound.
