It is an international metric temperature scale on which water freezes at 0° and boils at 100° under normal atmospheric conditions. The term "Celsius" is usually preferred to "centigrade," especially in technical contexts. Until 1948 the scale was known as centigrade when it was renamed in honour of Celsius, though in general usage (for example television weather forecasts) it was still called centigrade until quite recently.
Celsius refers to Anders Celsius, the Swedish Astronomer who developed the temperature scale with 100 degrees at the freezing point of pure water (actually its triple point) at normal pressure and 0 degrees at its boiling point. On his death in 1744 Linneaus reversed the scale.
-3 Celsius is warmer.
The answer is -20º celsius is colder than -18º celsius.
-60 Celsius is colder than -25 Celsius.
18 degrees Celsius is colder than 20 degrees Celsius.
8 Degrees Celsius is warmer than 2 degrees Celsius.
The opposite of Fahrenheit is spelled Celsius.
No, Celsius is a unit of temperature measurement on the Celsius scale. It is not the opposite of temperature, but a way to quantify it.
The spelling is "Fahrenheit", an English temperature scale, while "Celsius" is the metric scale. The measurements are not "opposite", merely on a different scale.
we have the same formula for their conversion
Not sure what you are asking unless you meant the opposite. 0 in Celsius is +32 in Fahrenheit = freezing 100 in Celsius is 212 in Fahrenheit = boiling point.
Celsius
The opposite of 15 degrees, in terms of angles on a circle, is 195 degrees. This is found by adding 180 degrees to 15 degrees, resulting in 15 + 180 = 195 degrees. In a broader context, the term "opposite" might also refer to the concept of negative in temperature, which would be -15 degrees Celsius or Fahrenheit.
-3 Celsius is warmer.
Celsius invented the celsius scale for temperature.
18 C
It is 28 degrees Celsius that is higher than 25 degrees Celsius
The difference between 1 degree Celsius and 2 degrees Celsius is 1 degree Celsius.
