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 is a microgram?
A microgram is a unit of mass in the metric system that is equal to one millionth of a gram. It is commonly used to measure very small amounts of substances, such as medications, vitamins, or pollutants. The symbol for microgram is μg. To put it into perspective, a single grain of table salt typically weighs around 58,500 micrograms.
