How do the Fahrenheit and Celsius temperature scales compare?
1 Answer
Fahrenheit = Celsius grades +273
The Fahrenheit scale is based on 32 °F for the freezing point of water and 212 °F for the boiling point of water, while the Celsius scale is based on -273.15 °C for absolute zero and 0.01 °C for the triple point of specially purified water.
The Fahrenheit scale is based on 32 °F for the freezing point and 212 °F for the boiling point of water. Thus, the boiling and freezing points of water are exactly 180 degrees apart.
The Celsius scale is based on exactly -273.15 °C for absolute zero and exactly 0.01 °C for the triple point of specially purified water, with 273.16 degrees between these two points.
On the Celsius scale, the freezing point of water is still 0 °C, and the boiling point of water is still 100 °C (but these are not the definitions). Thus, the boiling and freezing points of water are 100 degrees apart. Therefore
180 F° = 100 C° or
1 F° =
The formula to convert Celsius to Fahrenheit is F =
