The normal distribution is sometimes informally called the bell curve. However, many other distributions are bell-shaped (such as the Cauchy, Student's t, and logistic distributions).
One metric ton (also known as a 'Tonne') contains 1000 kg, or 2204 pounds. There are two other types of ton: One Imperial ton (or British ton) equals 2240 pounds, or 1016.3 kg. One short ton contains 2000 pounds, or 907.4 kilogrammes.
How many kilograms are in a metric ton? To differentiate between the different tons, the system has come up with the long ton, tonne and short ton. The long ton weighs 2,240 pounds, the tonne weighs 1,000 kilograms (2,204.6 pounds) and the short ton weighs 2,000 pounds (907.2 kilograms). The long ton and the tonne are commonly used in the United Kingdom for trade. The short ton is used in the United States.
