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.
A metric ton weighs 1,000 kilograms. A metric ton (t) is not part of the International System of Units but is approved for use. Ton can be spelled as tonne, which is the standard spelling in the metric system. Prior to metrication, the ton weighed 1,016 kilograms, or 2,240 pounds.
