# 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**.
