The scale is based on the freezing point and the boiling point of water (at some standard pressure); between those two temperatures, the scale is divided into 100 intervals. Centi means hundred.

The Celsius scale is also known as the Centigrade scale.
Centigrade
The Greeks had simple thermometers in the first century BC. Galileo Galilei (1564-1642) Italian physicist, invented a basic air thermometer. Daniel Gabriel Fahrenheit (1686-1736) was the German physicist who invented the alcohol thermometer in 1709, and the mercury thermometer in 1714. In 1724, he introduced the temperature scale that bears his name - Fahrenheit Scale. The Celsius scale, invented by Swedish Astronomer Anders Celsius (1701-1744), has 100 degrees between the freezing point (0 C) and boiling point (100 C) of pure water at sea level air pressure. The Celsius temperature scale is also referred to as the "centigrade" scale. Centigrade means "consisting of or divided into 100 degrees". The term "Celsius" was adopted in 1948 by an international conference on weights and measures.
The Celsius or centigrade scale runs from -273 deg C to you name it. 0 deg C is the freezing point of pure water 100 deg C is the boiling point of water. 15,000,000 deg C is the core temperature of the Sun The Kelvin scale (K) uses the same units. -273 deg C = 0 deg K. 0 deg K is also known as absolute zero, the point at which no further heat energy can be extracted from a system
Three temperature scales are in common use in science and industry. Two of those scales are SI metric: The degree Celsius (°C) scale was devised by dividing the range of temperature between the freezing and boiling temperatures of pure water at standard atmospheric conditions (sea level pressure) into 100 equal parts. Temperatures on this scale were at one time known as degrees centigrade, however it is no longer correct to use that terminology. [The official name was changed from "centigrade degree" to "Celsius degree" by the 9th General Conference on Weights and Measures (CGPM) in 1948.] The kelvin (K)temperature scale is an extension of the degree Celsius scale down to absolute zero, a hypothetical temperature characterized by a complete absence of heat energy. Temperatures on this scale are called kelvins, NOT degrees kelvin, kelvin is not capitalized, and the symbol (capital K) stands alone with no degree symbol. [The official name was changed to "kelvin" and symbol "K" by the 13th General Conference on Weights and Measures (CGPM) in 1967.] The degree Fahrenheit (°F)non-metric temperature scale was devised and evolved over time so that the freezing and boiling temperatures of water are whole numbers, but not round numbers as in the Celsius temperature scale.
