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.
The tonne (/ t Ê n / ( listen)) (non-preferred SI derived unit; SI symbol: t), commonly referred to as the metric ton in the United States, is a non-SI metric unit of mass equal to 1,000 kilograms; or one megagram (Mg); it is equivalent to approximately 2,204.6 pounds, 1.102 short tons (US) or 0.984 long tons (imperial).
