What is Weight / Mass?

Mass is the amount of matter in an object; in everyday language it is usually called weight. The SI unit is the kilogram (kg), with the gram and milligram for small amounts and the metric ton (1,000 kg) for large ones.

The imperial and US systems use the pound (lb), defined as exactly 453.59237 grams, and the ounce (oz), one sixteenth of a pound or about 28.35 grams. The US short ton (907 kg) and the British long ton (1,016 kg) should not be confused with the metric ton.
