Do you want to know the temperature conversion formula for every scale? If yes, then you are in the right place. In the field of science, they are many temperature conversion scales such as Kelvin, Celsius and Fahrenhei which we can easily be driven using formulae.
Today, I will show you how to convert a temperature from one scale to another using scientific formula and also show you how you can create a tool (calculator) that converts figures from one temperature scale to another on your website. You may see our step-by-step guide on the complete guide to website design (using Wix).
Temperature conversion formula is the formula that we can use to change or convert the value of a temperature from one unit or scale to another.
Let’s look at how to convert temperature from scale to another.
How to convert temperature from one scale to another
In Physics, Biology, Chemistry and other scientific subjects, we need to convert temperature scale in some cases when a particular problem is given for us to solve. When solving a temperature conversion relating problem, please note that according to:
- Kelvin scale: the freezing point of water is 273.15K and the boiling point is 373.15K.
- Fahrenheit scale: the freezing point of water is 32°F and the boiling point is 212°F.
- Celsius scale: the freezing point of water is 0°C and the boiling point is 100°C.
For more, please check the table below for how to convert temperature from one scale to another scale.
| Celsius to Fahrenheit | ° F = 9/5 ( ° C) + 32 |
| Kelvin to Fahrenheit | ° F = 9/5 (K – 273) + 32 |
| Fahrenheit to Celsius | ° C = 5/9 (° F – 32) |
| Celsius to Kelvin | K = ° C + 273 |
| Kelvin to Celsius | ° C = K – 273 |
| Fahrenheit to Kelvin | K = 5/9 (° F – 32) + 273 |
Please note that:
- Celsius and Fahrenheit are the same at -40°.
- Water boils at 100°C or 212°F.
- Water freezes at 0°C and 32°F.
- Absolute zero is 0 K.
- Celsius and Fahrenheit are degree scales.
- The degree symbol is not used to report temperature using the Kelvin scale.
How to derive remperature conversion formulae
There can be three main conversions of temperature which are:
- Conversion Between Celsius and Kelvin
- Conversion Between Fahrenheit and Kelvin
- Conversion Between Celsius and Fahrenheit
Celsius and Kelvin
- The temperature conversion formula for from Celsius to Kelvin is: K = C + 273.15
- The temperature conversion formula for from Kelvin to Celcius is: C = K − 273.15
Fahrenheit and Celsius
Fahrenheit to Celsius and Celsius to Fahrenheit formulas are listed below. These formulas will help to convert the temperature into required units.
- The temperature conversion formula from Fahrenheit to Celsius is: C = (F − 32) × 5⁄9
- The Temperature Conversion Formula from Celsius to Fahrenheit is: F = C(9⁄5) + 32
Fahrenheit and Kelvin
- The Temperature Conversion Formula for from Fahrenheit to Kelvin is: K = (F − 32) × 5⁄9 + 273.15
- The Temperature Conversion Formula from Kelvin to Fahrenheit is: F = (K – 273.15) × 9⁄5 + 32
How to convert temperature for very scale
The table below will help you know how the formula to use to convert temperature from one scale to another.
| Unit | Celsius | Fahrenheit | Kelvin |
|---|---|---|---|
| Celsius (C) | C (°) | C(9⁄5) + 32 | C + 273.15 |
| Fahrenheit | (F − 32) × 5⁄9 | F | (F − 32) × 5⁄9 + 273.15 |
| Kelvin | K – 273.15 | (K – 273.15) * 9/5 + 32 | K |
Solved mathematical examples on temperature conversion
Question 1: What is 30°C in Kelvin?
Solution:
The temperature conversion formula from Celsius to Kelvin is, K = C + 273.15
K = 30 + 273.15 K = 303.15
Question 2: Convert 50°C to °F.
Solution:
Celsius to Fahrenheit conversion formula is given by:
°F = °C(9⁄5) + 32
= 50 (9/5) + 32
= 90 + 32
= 122
Therefore, 50°C = 122°F
Question 3: Convert 113°F to Kelvin.
Solution:
Fahrenheit to Kelvin conversion formula is given by:
K = (F − 32) × 5⁄9 + 273.15
= (113 – 32) × (5/9) + 273.15
= 81 × (5/9) + 273.15
= 45 + 273.15
= 318.15
Therefore, 113°F = 318.15 K
Question 4: Convert 225 K to Celsius.
Solution:
Kelvin to Celsius conversion formula is given by:
C = K – 273.15
= 225 – 273.15
= -48.15
Therefore, 225 K = -48.15°C.
Tool to calculate or convert temperatures from one scale to another
If your website or blog has services that invite science students, you can help them to be able to easily convert a temperature from one scale to another when they simply enter figures (numbers or digits). That is, you can create a tool or calculator or temperature converter.
If you need advanced tool to calculate temperatures from any scale to another, you may contact us to code and design it for you.
I would like to show you a simple Python code to create a tool that converts temperatures from Celsius to Kelvin. Here is the code and its explanation.
/code
# Function to convert Celsius to Kelvin
def celsius_to_kelvin(celsius):
kelvin = celsius + 273.15
return kelvin
# Input: Celsius temperature
celsius_temp = float(input("Enter the temperature in Celsius: "))
# Conversion
kelvin_temp = celsius_to_kelvin(celsius_temp)
# Output: Kelvin temperature
print(f"{celsius_temp}°C is equal to {kelvin_temp}K.")The function, celsius_to_kelvin() takes a Celsius temperature as input and converts it to Kelvin using the formula K=C+273.15.
If you professionally implement the code above on your website or blog’s theme, people will be able to input a temperature in Celsius. Then the tool will calculate and prints the corresponding temperature in Kelvin. You may see our step-by-step guide on how to code a checkout page for an e-commerce website.
For your example, if the user inputs 30°C, the output will be 303.15K. If you need this tool on your website, feel free to contact us. We develop tools for different industries, let’s know what you want and we will turn it into reality.
