How much celsius is 30 fahrenheit

The Fahrenheit temperature scale is named for German physicist Daniel Gabriel Fahrenheit and is the measurement of temperature commonly used by the United States and its associated territories and by several nations in the Caribbean.

The Celsius temperature scale—originally called centigrade and later renamed for Swedish astronomer Anders Celsius— is used almost everywhere else in the world. To convert temperatures in degrees Fahrenheit to Celsius, subtract 32 and multiply by. 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.

Multiply By 5 2. Divide By 9 4. Turn 9 To 10 5. Half To 90 And 10 To 5 7. The exact conversion would be For a lower F temperature to start with, you don't have to add much. In this case, the exact conversion is 4. Easiest way: Google it. Type "convert x degrees Fahrenheit into Celsius" That goes for many measurements. For example, kg-pounds, m-inch and etc. It works both ways. Conversion of C to F.

Take the value of C, multiply it by 2. Example: 10C to F? It also is incorrect in other examples that I worked. Wish it worked because it's simple but not. Skip to main content. Convert F to C or C to F—and learn the formulas! By Catherine Boeckmann. The scientific definition of Celsius is now defined against degrees Kelvin. Zero degrees Celsius is One degree Celsius is equal to one Kelvin, so we can say that the boiling point of water is equal to Most things we measure — length, width, time etc.

We all know exactly how long zero centimeters or inches is, and can convert zero of any of those units into another type of unit very easily. Taking inches and centimeters as an example, to go from zero inches to 1 inch we need to add one inch. So far, so obvious. Similarly, to go from zero centimeters to 1 centimeter, we need only add 1 centimeter. The only difference between adding one inch or one centimetre is the amount of distance we're adding.

The relationship between an inch and a centimetre is that 1 inch is 2. So we can say that adding 1 inch is the same as adding 2. Temperature units aren't built in the same simple way, because they don't all start in the same place at zero.

It's not a difficult extra step, but it seems to be something that can cause confusion. As a rough rule of thumb: To go from Fahrenheit to Celsius, take 30 off the Fahrenheit value, and then half that number.
