What are the Most Common Temperature Conversion Formulas?
Celsius to Fahrenheit Formula
Knowing how to convert temperatures is important. A common need is changing Celsius to Fahrenheit, which is useful for understanding international data.
The formula for converting Celsius (°C) to Fahrenheit (°F) is:
F = (C × 9/5) + 32For example, let’s convert 25 degrees Celsius:
- First, multiply 25 by 9/5:
25 × (9/5) = 45. - Next, add 32 to the result:
45 + 32 = 77. - Therefore, 25°C is equal to 77°F.
Doing this math by hand can be slow. Our free online tool makes it easy. Just enter a value in Celsius to get the answer in Fahrenheit instantly. It saves time and helps you avoid mistakes.
Fahrenheit to Celsius Formula
You also may need to convert Fahrenheit to Celsius. The United States mainly uses Fahrenheit, while most other countries use Celsius. This conversion is key to understanding temperatures globally.
The formula for converting Fahrenheit (°F) to Celsius (°C) is:
C = (F - 32) × 5/9Here is an example converting 68 degrees Fahrenheit:
- First, subtract 32 from 68:
68 - 32 = 36. - Next, multiply the result by 5/9:
36 × (5/9) = 20. - Thus, 68°F is the same as 20°C.
Our eLearnSmart platform has a calculator for this so you don’t have to do the math yourself. You can use this tool and over 100 others for free on our site.
Kelvin Conversion Formulas
The Kelvin scale is very important in science. It is an absolute temperature scale, meaning its zero point is the coldest possible temperature [1]. This makes Kelvin conversions necessary for scientific and engineering calculations.
Here are the most common formulas for Kelvin conversions:
- Celsius to Kelvin (C to K):
To change Celsius to Kelvin, add 273.15 to the Celsius temperature.
K = C + 273.15For example, 20°C is
20 + 273.15 = 293.15 K. - Kelvin to Celsius (K to C):
To change Kelvin to Celsius, subtract 273.15 from the Kelvin temperature.
C = K - 273.15For instance, 300 K is
300 - 273.15 = 26.85°C. - Fahrenheit to Kelvin (F to K):
This conversion is a two-step process. First, convert Fahrenheit to Celsius, then convert Celsius to Kelvin.
K = (F - 32) × 5/9 + 273.15For 68°F: First,
(68 - 32) × 5/9 = 20°C. Then,20 + 273.15 = 293.15 K. - Kelvin to Fahrenheit (K to F):
This is also a two-step process. First, convert Kelvin to Celsius, then convert Celsius to Fahrenheit.
F = (K - 273.15) × 9/5 + 32For 293.15 K: First,
293.15 - 273.15 = 20°C. Then,(20 × 9/5) + 32 = 68°F.
These two-step conversions can seem tricky. But our online temperature tools handle them for you. Use our free calculators to get fast and accurate results for any temperature conversion.

Frequently Asked Questions
What is the temperature conversion formula to Fahrenheit?
To get a temperature in Fahrenheit (°F), you usually start with either Celsius (°C) or Kelvin (K).
Celsius to Fahrenheit Conversion
To change Celsius to Fahrenheit, you multiply the Celsius temperature by 9/5 (or 1.8) and then add 32.
- Formula:
°F = (°C × 9/5) + 32 - Example: If it’s 20°C, then (20 × 9/5) + 32 = 36 + 32 = 68°F.
Kelvin to Fahrenheit Conversion
To convert Kelvin to Fahrenheit, you first change Kelvin to Celsius. Then, you convert that Celsius temperature to Fahrenheit.
- Step 1: Kelvin to Celsius:
°C = K - 273.15 - Step 2: Celsius to Fahrenheit: Use the formula above with the new Celsius value.
- Combined Formula:
°F = ((K - 273.15) × 9/5) + 32 - Key Point: Absolute zero is the coldest possible temperature. It is 0 Kelvin, which is the same as -273.15°C [4].
