Celsius to Fahrenheit degrees conversion formula is Fahrenheit = Celsius * 1.8 + 32.
For converting from degrees Celsius to degrees Fahrenheit, multiply the degrees 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 °C and °F ratio is calculated as (boiling point for Fahrenheit, 212°F - freezing point for Fahrenheit, 32°F) / (boiling point for Celsius, 100°C - freezing point for Celsius, 0°C), that is 180 / 100 = 1.8 ratio between Celsius and Fahrenheit.
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".
