Temperature Definition: | |
Temperature is the average of kinetic energy of the movement of particles such as atoms or molecules. It is a numerical representation of how cold or hot something is. | |

F = Fahrenheit (°F) | C = Celsius (°C) | K = Kelvin
F = C(1.8) + 32
C = (F-32)/1.8
K = C + 273.15 |

Worldwide use: | The Celsius scale, already widely used in Europe, replaced the Fahrenheit scale in most countries during the mid-to-late 20th century, although Fahrenheit remains the official scale of the United States, Cayman Islands and Belize. | The Fahrenheit scale was replaced by the Celsius scale in most countries during the mid to late 20th century, although Fahrenheit remains the official scale of the United States, Cayman Islands and Belize. Canada retains Fahrenheit as a supplementary scale that can be used alongside Celsius, and in the UK the Fahrenheit scale continues to be used informally. |
Definition: | Although initially defined by the freezing point of water (and later the melting point of ice), the Celsius scale is now officially a derived scale, defined in relation to the Kelvin temperature scale.
Zero on the Celsius scale (0 °C) is now defined as the equivalent to 273.15 K, with a temperature difference of 1 deg C equivalent to a difference of 1 K, meaning the unit size in each scale is the same. This means that 100 °C, previously defined as the boiling point of water, is now defined as the equivalent to 373.15 K.
The Celsius scale is an interval system but not a ratio system, meaning it follows a relative scale but not an absolute scale. This can be seen because the temperature interval between 20 °C and 30 °C is the same as between 30 °C and 40 °C, but 40 °C does not have twice the air heat energy of 20 °C.
A temperature difference of 1 deg C is the equivalent of a temperature difference 1.8°F. | Fahrenheit is a thermodynamic temperature scale, where the freezing point of water is 32 degrees Fahrenheit (°F) and the boiling point 212°F (at standard atmospheric pressure). This puts the boiling and freezing points of water exactly 180 degrees apart. Therefore, a degree on the Fahrenheit scale is 1/180 of the interval between the freezing point and the boiling point of water. Absolute zero is defined as -459.67°F.
A temperature difference of 1°F is the equivalent of a temperature difference 0.556°C. |

There are three different scales for temperature conversions, namely Fahrenheit, Celsius, and Kelvin. We, at Online Conversions, offer you an easiest way to convert temperature units. Our temperature unit conversion, an online conversion calculator, enables you to convert units of temperature between various scales. Converting Fahrenheit to Celsius, Kelvin to Fahrenheit, or Rankine to Reaumur will be a matter of few seconds.
With the help of our temperature unit conversion tool one can access and convert some of the typical temperatures with no effort. Using our temperature conversion tool is also very easy as it just requires to type value into the appropriate edit box then the converter will convert the value into the other systems automatically.
Conversion between different temperature scales in your head is not so simple. One needs to remember proper appropriate conversion formula. Like, in order to convert Fahrenheit to Celsius the given value should be first deducted by 32, the multiplied by 5 and then divided by 9. In the similar fashion, when it comes to convert Celsius to Fahrenheit then the given value is first multiplied by 9, then resultant is divided by 5 and then the obtained value is added with 32. Though, the calculation is not much tricky but it requires a piece of paper and few minutes to calculate. Hence, utilizing our user-friendly temperature unit conversion tool is smart step as it gives you reliable and accurate results. |
