About metric grain
The metric grain (or pearl grain) is a unit of mass in the metric system equal to 0.050 × 10-3 kilograms (1 metric grain = 0.050 × 10-3 kg), the base unit of mass in the International System of Units (SI).
The metric grain (metric gr) is also equal to 0.050 grams (g), or 50 milligrams (mg) or 50,000 micrograms (μg) (SI units of mass), or about 1.102311 × 10-4 pounds (lb) or 0.001763698 ounces (oz), which are US customary / Imperial units of mass.
The grain definition varies depending on the system of units used, as follows:
- 1 grain = 1 avoirdupois grain = 1 troy grain = 1 Apothecaries grain = 64.79891 × 10-3 grams
- 1 metric grain = 1 pearl grain = 50 × 10-3 grams = 1/4 (metric) carats
The metric grain (or pearl grain) is used as a unit of mass for pearls and diamonds.
