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.
Metric units of mass. Mass is measured in grams (g), kilograms (kg) and tonnes. These are known as metric units of mass. 1 kg = 1000 g. 1 tonne = 1000 kg. Remember when estimating mass: 100g is about the mass of a small apple.1 kg is the mass of a bag of sugar or a litre of water.etric units of mass.
