. 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.
the temperature for hot oatmeal in Celsius is about 74 Celsius
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
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.
