. Celsius is a way to portray temperature, just like Fahrenheit. One isn't more right than the other. They are both used, just in different places.
It's the same actual temperature as -40 degrees Fahrenheit.
That's correct. In the Fahrenheit and Celsius temperature scales, a given temperature in Fahrenheit will be higher than the equivalent temperature in Celsius. For example, 50 degrees Fahrenheit is a higher temperature than 10 degrees 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.
That depends on the temperature. At 20 degrees Celsius speed of sound is 343 meters per second.
There can be no conversion because -499°C is not an actual temperature. The lowest temperature possible for matter is absolute zero, which is -273.15°C or -459.7°F
the temperature for hot oatmeal in Celsius is about 74 Celsius
If the temperature decreases by 30 degrees Celsius from 20 degrees Celsius, the new temperature will be -10 degrees Celsius.
Zero Celsius
No, when the temperature in Celsius doubles from 10°C to 20°C, the temperature in Fahrenheit does not double. The relationship between Celsius and Fahrenheit temperatures is not linear, so a doubling in Celsius temperature does not equate to a doubling in Fahrenheit temperature.
Anders Celsius, a Swedish astronomer, invented the Celsius temperature scale in 1742.
5 degrees below 2 Celsius is -3 Celsius.
No, that is actual a little cold for human body temperature. It would matter who it is that is running this temperature because some fevers can be cold fevers.
