Other High School. In every science class, you must know how to use and interpret the Celsius temperature scale. But this can be difficult for students who are used to using Fahrenheit instead. How do you convert Celsius to Fahrenheit? What about Fahrenheit to Celsius?

We answer these questions below, giving you the mathematical formulas for converting between these two temperature units, a handy conversion chart, and a quick conversion trick you can use without having to grab a calculator.

Moreover, unlike Celsius, it is not typically used in science. Here are the formulas used to convert Celsius to Fahrenheit and Fahrenheit to Celsius. These formulas will give you the exact conversion from one unit of temperature to the other:. To find out what this equals in Celsius, simply plug By memorizing some of the most common temperatures that come up in daily life, you should have no problem being able to convert from Celsius to Fahrenheit and vice versa.

It's gettin' hot in here. Below is a conversion chart listing some of the most commonly used temperatures in everyday life when converting from Celsius to Fahrenheit.

### Celsius Formula

Source: NIST. As you can see from this chart, Fahrenheit temperatures are typically a lot higher than their equivalent Celsius temperatures are. Also, notice how the difference between Celsius and Fahrenheit starts to get smaller the lower you go in temperature—until, that is, they're the exact same!

This point is called parity, meaning the two scales use the same value to represent the same temperature. Unfortunately or fortunately, since this is pretty cold! The lower you go after parity i. If you find yourself needing to quickly convert Celsius to Fahrenheit, here is a simple trick you can use: multiply the temperature in degrees Celsius by 2, and then add 30 to get the estimated temperature in degrees Fahrenheit.

This rule of thumb is really useful and also pretty accurate for most weather-related temperatures. Of course, expect the actual temperature to be a few degrees off, but for the most part, this is a reliable and easy way to convert temperatures in your head fast. If you want to convert Fahrenheit to Celsius, do the opposite: subtract 30 from the temperature in degrees Fahrenheit, and then divide by 2 to get the temperature in degrees Celsius.

Celsius and centigrade are two names for essentially the same temperature scale with slight differences. The centigrade scale is divided into degrees based on dividing the temperature between which water freezes and boils into equal gradients or degrees. The word centigrade comes from "centi-" for and "grade" for gradients. The centigrade scale was introduced in and remained the primary scale of temperature until Since the "grade" was in use as a unit including the "centigrade"a new name was chosen for the temperature scale: Celsius.

A degree Celsius or a Kelvin is what you get when divide the thermodynamic range between absolute zero and the triple point of a specific type of water into There is a 0. The temperature scale created by Anders Celsius in was actually the reverse of the modern Celsius scale. Celsius' original scale had water boil at 0 degrees and freeze at degrees.

Jean-Pierre Christin independently proposed at a temperature scale with zero at the freezing point of water and was the boiling point Celsius' original scale was reversed by Carolus Linnaeus inthe year in which Celsius died. When the scale was extended from 0 to degrees for temperature, centigrade was more properly hectograde.

The public was largely unaffected by the confusion. Even though the degree Celsius was adopted by international committees inweather forecasts issued by the BBC continued to use degrees centigrade until February ! Share Flipboard Email. Anne Marie Helmenstine, Ph.

## What's the Easiest Way to Convert Fahrenheit to Celsius?

Centigrade The Celsius scale is a type of centigrade scale. A centigrade scale has degrees between the freezing and boiling points of water. The original Celsius scale actually had a boiling point of 0 degrees and freezing point of degrees. It ran in the opposite direction of the modern scale!

That gets you in the right ballpark immediately, and I never found it important to distinguish between, say, 63 and 65 degrees F - especially because other factors, like wind speed and humidity, will make a much larger difference in how hot or cold you actually feel. That range - a mere seven numbers to commit to memory - is really all you need; anything below C is "too damn cold", and anything above 40C is "too damn hot". Celsius to Fahrenheit 10 x 1. Round to nearest tenth where necessary.

If you need a more accurate reading just add or subtract 1. Here's a much simpler method for those not keen on algebraic equations. For a good approximate: To convert centigrade to Fahrenheit: simply double the degrees in C, and add To convert Fahrenheit to Centigrade: simply subtract minus, or take away 30 from degrees in F, and half it for example: 70 deg F i. There are three popular temperature scales used in math and science.

You will often find yourself having to convert units between these scales. Using examples, we will learn how to perform these conversions, and also relate temperatures expressed in Kelvins, degrees Celsius and degrees Fahrenheit. The benefit of using this formula is that it is easier to use in your head and the answer is exact; So it works in a calculator too! Using Method 5 Divided By 9 1.
