What is Gram?
Grams (g) = Kilograms (kg) × 1000
Tyes of Gram
- Metric Gram: The standard unit of mass in the International System of Units (SI), equal to 1/10001/1000 of a kilogram.
- Troy Gram: Used in the measurement of precious metals, particularly gold and silver, in the troy weight system. One troy gram is slightly heavier than a metric gram due to differences in the measurement system.
- Atomic Mass Unit (amu): A unit of mass used in chemistry and physics, equal to approximately the mass of a proton or neutron, approximately 1.66054×10−241.66054×10−24 grams.
