Curiously, Celsius created the reverse of the modern scale, treating 0 as the boiling point of water and 100 as the freezing point of water. Fahrenheit can be abbreviated as For a more accurate answer please select 'decimal' from the options above the result.Note: You can increase or decrease the accuracy of this answer by selecting the number of significant figures required from the options above the result.Note: For a pure decimal result please select 'decimal' from the options above the result.There's a simple rule to convert Fahrenheit to Celsius that should be good enough for general use. . Some would consider a quick estimate the easiest way to convert a Fahrenheit temperature to a Celsius temperature. Inverse Conversion Only 18 years after Daniel Fahrenheit’s breakthrough, another scientist named Anders Celsius developed a second system of temperature measurement and a much more intuitive one at that. If you're from almost anywhere else, you likely favor Celsius, where 0 degrees is only pretty cold, 50 degrees is unspeakably hot, and 100 degrees happens on a stove, not outside.If you were wondering if there is a temperature where Fahrenheit and Celsius are the same, it's at 40 below zero, also known as -40 or negative 40. = 50 °F = The Fahrenheit scale is a temperature scale that defines the melting point of water as 32 degrees and the boiling point of water at 212 degrees. You can use this equation to show that 100 degrees Celsius is equal to 212 degrees Fahrenheit.Start with the temperature in Celsius (e.g., 100 degrees).Multiply this figure by 1.8 (e.g., 100 * 1.8 = 180).If you really want an easy way to convert temperatures, you can use this Fahrenheit to Celsius conversion chart where the math has already been done for you. So far, so obvious.Temperature units aren't built in the same simple way, because they don't all start in the same place at zero. have one thing in common – their values all start from zero.
