Temperature Calculator + Online Solver With Free Steps

The Temperature Calculator is used to convert a temperature from one scale to another scale. It takes a temperature in a particular scale as input and outputs the temperature in the scale required by the user.

It provides additional temperature conversions in degrees Fahrenheit, degrees Celsius, degree Rankine, degree Reaumur and degrees Romer.

The Calculator is handy as it provides additional information such as how much the output temperature is above the average body temperature for a healthy human.

What Is a Temperature Calculator?

The Temperature Calculator is an online tool that is used to perform temperature conversions from one scale to another.

The Calculator also provides the values of thermodynamic energy E, Black Body Energy Flux Φ, and the approximate luminous exitance from a planar black body radiator perpendicular surface.

How To Use the Temperature Calculator

The user can use the Temperature Calculator by following the steps given below.

Step 1

The user must first enter the temperature value and the scale from which the temperature needs to be converted. It should be entered in the particular box labeled as What is.

In the default example, the temperature entered is 100 Fahrenheit.

Step 2

The user must now enter the temperature scale in which the temperature needs to be converted.

It should be entered in the specified block titled as in. The default example needs the temperature to be converted in Kelvins.

Step 3

The user must now press the Submit button for the calculator to process the temperature value and the scale on which the temperature needs to be converted.

Output

The calculator computes the output in the following eight windows.

Input Interpretation

The calculator interprets the input and shows it in this window. For the default example, it shows “convert 100 °F to Kelvins.”

Result

This window provides the temperature value in the scale required by the user. In the default example, the calculator uses the formula given below to convert Fahrenheit to Kelvin scale:

\[ \text{ y Kelvins } = ( \text{ x Fahrenheit } + 459.67 ) × \frac{5}{9} \]

Where x is the temperature in Fahrenheit and y is the temperature in Kelvins. Putting the value of x as 100 Fahrenheit, the calculator computes the value of y as follows:

\[ \text{ y Kelvins } = ( 100  + 459.67 ) × \frac{5}{9} \]

y Kelvins = 310.9 K

The Kelvin temperature is an absolute zero temperature that does not provide any negative values. It is important to convert the temperature to Kelvin as all the gas laws work on the Kelvin scale.

Additional Conversions

The calculator also converts the temperature in Kelvins, Rankine, Reaumur, Romer, and Fahrenheit. For the default example, the temperature conversions for 100 Fahrenheit are given below.

Degrees Celsius = 37.778 °C

Degree Rankine = 559.67 °R

Degree Reaumur = 30.222 °Re

Degrees Romer = 27.333 °Ro

Comparisons as Temperature

The calculator also compares the output temperature with 0.7778 K which is above the traditional value associated with the “normal” body temperature of a healthy human.

It also displays the average body temperature of a human body and how much the temperature is above or below the conventional US room temperature.

Interpretation

The interpretation window shows the quantity which is converted which is temperature.

Basic Unit Dimensions

The Basic Unit Dimension shows the dimensions of the input temperature and the temperature required by the user.

Corresponding Quantities

The Corresponding quantities include the values of thermodynamic energy E, Black Body Energy Flux Φ, and the approximate luminous exitance from a planar black body radiator perpendicular surface.

The formula for thermodynamic energy E used by the calculator is as follows:

E = kT

Where k is a factor that denotes the amount of heat required to increase the temperature of the system.

For the default example, the thermodynamic energy comes out to be 27meV.

For the Black Body Energy Flux Φ, the calculator uses the formula:

Φ = σT$^{4}$ 

The calculator shows the value for the Black Body Energy Flux Φ as 530 W/m$^2$ for the default example.

The calculator calculates the approximate luminous exitance from a planar black body radiator perpendicular surface as 1.9 × 10$^{-20}$ lx of the default example.

Nearest Corresponding Gas Marks

The calculator also displays the nearest corresponding gas marks. For the default example, the nearest corresponding gas mark for thermostat 1 is 30 °C.

Solved Example

The following example is solved through the Temperature Calculator.

Example 1

Convert 160 degrees Celsius in Kelvins. Calculate the Black Body Energy Flux, thermodynamic energy, and the approximate luminous exitance from a planar black body radiator perpendicular surface.

Also find the additional temperature conversions in Rankine, Reaumur, Romer, and the Fahrenheit scale.

Solution

The user must first enter the temperature which needs to be converted which is 160 Celsius in the example.

The user must now enter the temperature scale in which the temperature needs to be changed. The scale specified in the example is the Kelvin scale.

After pressing the “Submit” button, the calculator shows the input interpretation as “convert 160 °C to Kelvins.

The Result window shows the temperature in Kelvin to be 433.2 K. The calculator also shows the additional temperature conversions as follows:

Degrees Fahrenheit = 320 °F

Degree Rankine = 7799.67 °R

Degree Reaumur = 128 °Re

Degrees Romer = 91.5 °Ro

In the Comparisons as Temperature window, the calculator displays 72.78 K below the autoignition temperature of book paper in Ray Bradbury’s famous novel.

It also shows (60 to 90 K) below the autoignition temperature of paper and 33 K above the hottest temperature of a Concorde nose tip.

The calculator computes the thermodynamic energy to be 37meV and the black body energy flux to be 1996 W/m$^{2}$.

It also shows the approximate luminous exitance from a planar black body radiator perpendicular surface as 2 × 10$^{-12}$ lx. The corresponding gas mark for the 160 °C temperature is the gas mark 3 and the stufe 1 1/4.
