Twenty-seven degrees Celsius is equivalent to 80.6 degrees Fahrenheit. To convert from Celsius to Fahrenheit, multiply the degrees Celsius by nine, divide by five and add 32.
The Celsius scale is part of the metric system used in most countries of the world, while the United States primarily uses the Fahrenheit scale.
Daniel Gabriel Fahrenheit developed the Fahrenheit scale in the early 1700s. According to this scale, the freezing point of water is 32 degrees and the boiling point of water is 212 degrees. In the Celsius scale, developed in 1742 by Swedish astronomer Andres Celsius, the freezing point of water is 0 degrees while the boiling point of water is 100 degrees.
