Understanding Grams and Pounds: An Overview
What is a Gram?
A gram (g) is a metric unit of mass used worldwide, especially in scientific and everyday contexts. It is part of the International System of Units (SI) and is defined as one-thousandth of a kilogram. The gram is widely used in cooking, pharmaceuticals, jewelry, and other fields requiring precise measurement.
What is a Pound?
The pound (lb) is a unit of weight or mass used primarily in the United States, the United Kingdom, and some other countries.

Applying this to 900 grams:
\[
\text{Pounds} = \frac{900}{453.59237} \approx 1.984
\]
Therefore, 900 grams is approximately 1.984 pounds.
