- Thermometer scale in which the freezing point of water is 0°C and the boiling point of water at sea level is 100°C. The Centigrade scale is used around most of the world to indicate the temperature on a thermometer while the Fahrenheit scale is still obstinately in use in the US. This anachronism requires conversion from Centigrade (°C) to Fahrenheit (°F), and vice versa. One degree °C = (5/9)(°F - 32). One degree °F = (9/5)(°C) + 32.
* * *1. Basis of the former temperature scale in which 100 degrees separated the melting and boiling points of water. See Celsius scale. 2. One hundredth of a circle, equal to 3.6° of the astronomical circle. [L. centum, one hundred, + gradus, step, degree]
* * *cen·ti·grade 'sent-ə-.grād, 'sänt- adj relating to, conforming to, or having a thermometer scale on which the interval between the freezing and boiling points of water is divided into 100 degrees with 0° representing the freezing point and 100° the boiling point <10° \centigrade> abbr. C compare CELSIUS
* * *cen·ti·grade (senґtĭ-grād) [centi- + L. gradus a step] consisting of or having 100 gradations (steps or degrees); see under scale.
