Celsius to Fahrenheit degrees conversion formula is Fahrenheit = Celsius * 1.8 + 32.
To convert from degrees Celsius to Fahrenheit, multiply the celsius by 1.8 (the ratio between °C and °F) and add 32 (32 is the difference between freezing point of °F and freezing point of °C).
For example, to convert from 30 °C to °F, multiply the Celsius value by 1.8 and add 32, that is: 30 °C * 1.8 + 32 = 86 °F .
The 1.8 Celsius to Fahrenheit ratio means for each Celsius degree there are 1.8 Fahrenheit degrees and it is calculated by dividing the difference between boiling and freezing points for each of these temperature scales, that makes (212 °F - 32 °F) / (100 °C - 0 °C) = 1.8 .
Celsius (also known as centigrade) is a temperature scale with the freezing point of water is 0 degree and the boiling point of water is 100 degrees under standard atmospheric pressure (101.325 kPa). The absolute zero temperature is -273.15 °C. The symbol for Celsius scale is "°C".
Fahrenheit is a temperature scale with the freezing point of water is 32 degrees and the boiling point of water is 212 degrees under standard atmospheric pressure (101.325 kPa). The absolute zero temperature is -459.67 °F. The symbol for Fahrenheit scale is "°F".
