what is centigrade temperature

Centigrade temperature is an old-fashioned name for Celsius temperature. Celsius is the most common temperature scale in the world and the simplest to understand. It is based on the freezing point of water, which is 0°C, and the boiling point of water, which is 100°C. The Celsius scale was invented and named after Swedish scientist Anders Celsius in 1742. The degree Celsius is denoted as °C and is always written with the ° symbol next to the C and a space after the number so that 20 degrees Celsius is written 20 °C. The Fahrenheit and Kelvin scales are also commonly used temperature scales.
