On a scale, one gramme weighs exactly one gramme. One gramme equals one-thousandth of a kilogramme. If the scale is calibrated in other units, one gramme equals 0.0357 ounces.
The metric system’s units of mass are the kilogramme and the gramme. Except for the United States, Liberia, and Myanmar, the metric system is the standard system of measuring across the world. In the United States, the pound and the ounce are the weight units, which are roughly equivalent to mass units. A single ounce weighs 28.35 grammes, and one pound contains sixteen ounces. Consequently, 1 pound is equal to 453.6 grammes.
