The Fahrenheit scale, although very popular in the US has an intriguing history and varied worldwide adoption scenarios. While the US sticks to it, most other countries do not and its usage is also often combined with other scales in various parts of the world. The History The Fahrenheit scale was developed by Daniel Fahrenheit who born in the year 1686 and lived until 1736. The Dutch physicist, engineer and glass blower had actually performed precise calculations in the early 18th century to arrive at the absolute zero of the Fahrenheit scale and although it may appear random, the scale was based on solid scientific choices that make the number 32 (degree)°F the freezing point of water on the scale. He wanted to create a temperature scale that defined fixed temperature points including the starting (absolute zero) and three important points which include the absolute zero, which is the coldest possible temperature, the temperature of freezing water and also the temperature of the human body. An older system invented by Ole Christensen Romer, twenty years earlier formed the basis of these choices. When water is placed at sea level and under standard atmospheric pressure, it boils at approximately 212 (degree)°F according to the original scale exactly 180 higher than the freezing point of water. Similarly, the human body temperature is difficult to precisely determine as it varies depending on various factors such as the age of the person, the time of the day, the body's rate of metabolism etc. However, this too was adjusted for accuracy from the original 96 (degree)°F to 98 (degree)°F. The Fahrenheit scale is now defined by only the two fixed temperature points of the freezing point of water into ice, which is defined as 32 (degree)°F and the point at which water boils into water vapor, which is defined 212 (degree)°F. Both these temperature points are considering sea level and the standard atmospheric pressure. Adoption In comparison, although the Celsius temperature scale came into being at about the same time, it was not widely adopted for several decades. Its adoption finally accelerated when several countries around the world switched to the metric system in the 1960-70s. Until the late 1960s the Fahrenheit scale was used in the meteorological domain as well as the industrial establishment and the medical community in most English-speaking nations but in the 1970s almost all these nations switched to the Celsius scale. This change was so rapid that at the end of the 20th century, the Fahrenheit scale was only officially used in the United States of America and a few smaller regional states. International Scenario Canada has legislation that favors the Celsius scale but also maintains the legal definitions for the older imperial units. Weather reports in the country usually include the Celsius scale and a few references to the Fahrenheit temperatures. Even thermometers used in Canada show reading on both Celsius and Fahrenheit scales. On the other hand, the European Union has made it compulsory to use degrees Celsius when using a temperature reference in any public announcements and communications be it health, administrative or the public safety departments. It only allows the use of the Fahrenheit scale temperature points as a supplementary unit. In the UK certain unregulated sectors including journalism, follow no fixed pattern and references to both scales appear together or side by side in the written material. While some newspapers use the Celsius temperatures first on their weather page, followed by the Fahrenheit temperature, in brackets, other newspaper may not use the Fahrenheit scale at all on their weather reports and some go as far as to have several metrics listed and accompany it with a Temperature Scale conversion table. Conversion For the Fahrenheit scale: Water's freezing point = 32 (degree)°F Water's boiling point = 212 (degree)°F Therefore, One degree on Fahrenheit scale = 1180 of this interval. For the Celsius scale: The difference between the freezing point and the boiling point of water = 100 degrees. Therefore an interval of 1 (degree)Fahrenheit = an interval of 5/9 (degree)Celsius. Absolute zero on the Celsius and Fahrenheit scales are − (degree)C and − (degree)°F respectively. Therefore an exact formula for conversion would be: the temperature T in degrees Celsius or (degree)°C is equal to temperature T in degrees Fahrenheit or (degree)F minus 32, times 5/9. This is the simplest formula for converting temperatures between the Celsius and Fahrenheit scales. Quick Celsius (°C) / Fahrenheit (°F) Conversion: measure/images/ Type a value in either box Or use the slider Or the Interactive Thermometer Or this method: °C to °F Divide by 5, then multiply by 9, then add 32 °F to °C Deduct 32, then multiply by 5, then divide by 9 (Explanation Below ...) Typical Temperatures (only bold are exactly the same) °C °F Description 220 430 Hot Oven 180 360 Moderate Oven 100 212 Water boils 40 104 Hot Bath 37 Body temperature 30 86 Beach weather 21 70 Room temperature 10 50 Cool Day 0 32 Freezing point of water −18 0 Very Cold Day −40 −40 Extremely Cold Day (and the same number!) Some Tricks: Daily Temperatures: these three conversions "flip the digits" (accurate within 1°): °C °F 28 ⇄ 82 16 ⇄ 61 04 ⇄ 40 Oven Temperatures: in the range 150 to 200 °C we can double °C to get °F (accurate within 8°F): °C °FEstimate °FActual 200 400 392 180 360 356 160 320 320 150 300 302 Going the other way: for the range 300 to 400 °F we can halve °F to get °C (accurate within 4°C). Explanation There are two main temperature scales: °C, the Celsius Scale (part of the Metric System, used in most countries) °F, the Fahrenheit Scale (used in the US) They both measure the same thing (temperature!), but use different numbers: Boiling water (at normal pressure) measures 100° in Celsius, but 212° in Fahrenheit And as water freezes it measures 0° in Celsius, but 32° in Fahrenheit Like this: Looking at the diagram, notice: The scales start at a different number (0 vs 32), so we will need to add or subtract 32 The scales rise at a different rate (100 vs 180), so we will also need to multiply And so, to convert: from Celsius to Fahrenheit: first multiply by 180100, then add 32 from Fahrenheit to Celsius: first subtract 32, then multiply by 100180 180100 can be simplified to 95, and 100180 can be simplified to 59, so we get this: °C to °F: Divide by 5, then multiply by 9, then add 32 °F to °C: Subtract 32, then multiply by 5, then divide by 9 Example: Convert 25° Celsius (a nice warm day) to Fahrenheit First: 25° / 5 = 5 Then: 5 × 9 = 45 Then: 45 + 32 = 77° F Example: Convert Fahrenheit (normal body temperature) to Celsius First: − 32 = Then: × 5 = 333 Then: 333 / 9 = 37° C We can swap the order of divide and multiply if we want, but don't change the add or subtract. So this is also OK: Example: Convert Fahrenheit to Celsius (again) First: − 32 = Then: / 9 = Then: × 5 = 37° C(Same answer as before, was it easier or harder this way?) We can write them as formulas: Celsius to Fahrenheit: (°C × 95) + 32 = °F Fahrenheit to Celsius: (°F − 32) × 59 = °C Other Methods That Work Use instead of 9/5 9/5 is equal to so we can also use this method: Celsius to Fahrenheit: °C × + 32 = °F Fahrenheit to Celsius: (°F − 32) / = °C To make "× easier we can multiply by 2 and subtract 10%, but it only works for °C to °F: Celsius to Fahrenheit: (°C × 2) less 10% + 32 = °F Example: Convert 20° Celsius (A nice day) to Fahrenheit 20x2 = 40 less 10% is 40−4 = 36 36+32 = 68° F Add 40, Multiply, Subtract 40 Since both scales cross at −40° (−40° C equals −40° F) we can: add 40, multiply by 5/9 (for °F to °C), or 9/5 (for °C to °F) subtract 40 Like this: Celsius to Fahrenheit: Add 40, multiply by 9/5, then subtract 40 Fahrenheit to Celsius: Add 40, multiply by 5/9, then subtract 40 Example: Convert 10° Celsius (A cool day) to Fahrenheit 10+40 = 50 50×9/5 = 90 90−40 = 50° F Quick, but Not Accurate Celsius to Fahrenheit: Double, then add 30 Fahrenheit to Celsius: Subtract 30, then halve Examples °C → °F: 0° C → 0+30 → 30° F (low by 2°) 10° C → 20+30 → 50° F (exact!) 30° C → 60+30 → 90° F (high by 4°) 180° C → 360+30 → 390° F (high by 34°, not good) Examples °F → °C: 40° F → 10/2 → 5° C (almost right) 80° F → 50/2 → 25° C (low by about 2°) 120° F → 90/2 → 45° C (low by about 4°) 450° F → 420/2 → 210° C (low by about 22°, not good) Footnote: Temperature is a measure of how fast an object's particles are moving. 1041, 1042, 1043, 1044, 3724, 3725, 3726, 3727, 3728, 3729 101 °F = °C(to 2 decimal places) 101 degrees Fahrenheit converts to degrees Celsius How To Convert 101 Fahrenheit To Celsius Using the Fahrenheit to Celsius formula: Celsius (°C) = (Fahrenheit - 32) / this example shows how to convert a temperature of 101 degrees Fahrenheit to Celsius (101 F to C).
