Our Celsius to Fahrenheit calculator will help you stay on top of the difference between the two. We include some history of these temperature scales and the underlying definitions.
Celsius Definition
Celsius scale is also known as the centigrade scale. Celsius is a temperature scale used by the International System of Units and it is used worldwide, with the exception of the United States, Bahamas, Belize and Cayman Islands.
From 1743, the Celsius scale is based on a temperature of 0°C for the freezing point of water and 100 °C for the boiling point of water at standard atmospheric pressure.
Fahrenheit Definition
The scale of temperature known as Fahrenheit originated from a Garman physicist named Daniel Gabriel Fahrenheit (1686–1736).
On the Fahrenheit scale, the freezing level of water is at 32 degrees Fahrenheit (℉) while the boiling point is at 212 ℉. These assume that standard atmospheric pressure is constant.
The exact difference between boiling and freezing points of water is 180 degrees, which a degree on the Fahrenheit scale is 1⁄180 of the interval between freezing and boiling. Physicist Fahrenheit wanted a degree of temperature that took into consideration freezing water, human body temperature, and the coldest point that Fahrenheit could continuously cool a solution of water, ice, salt and ammonium chloride.
How to convert Celsius to Fahrenheit
The temperature in degrees Fahrenheit (°F) is equal to the temperature in degrees Celsius (°C) times 9/5 plus 32.
The formula for the conversion of Celsius to Fahrenheit is as follows:
T(°F) = T(°C) × 9/5 + 32
or
T(°F) = T(°C) × 1.8 + 32
How to convert Fahrenheit to Celsius
Thus, the formula for the conversion of Fahrenheit to Celsius is as follows:
T(°C) = (T(°F) – 32) × 5/9
or
T(°C) = (T(°F) – 32) / (9/5)
or
T(°C) = (T(°F) – 32) / 1.8
Knowing the history of Fahrenheit vs Celsius is important to help you remember the difference between the two.
When you are traveling abroad to a country with a different temperature scale, you should now know exactly how to calculate the translated degrees.
