Performing a temperature conversion from Celsius to Kelvin is one of the simplest calculations you can do. Unlike other conversions that require complex multiplication, these two scales move at the exact same rate.
The Kelvin scale was named after the physicist William Thomson, also known as Lord Kelvin. It is the primary unit of measurement in the physical sciences. To find the temperature in Kelvin, you simply add 273.15 to your Celsius degree.
Let's convert 5 degrees Celsius (°C) to Kelvin.
Using the formula above: 5 + 273.15 = 278.15
Therefore, 5 degrees Celsius is equal to 278.15 Kelvin.
Wondering how to convert a temperature from Celsius (°C) to Fahrenheit (°F)? It's easy to do with a simple formula. While the numbers might seem tricky at first, the calculation is very straightforward.
The most common formula to convert Celsius to Fahrenheit is:
Here's how to use that formula in three easy steps:
And you're done! So, 20°C is equal to 68°F.
You can use this simple method whenever you need to convert a temperature from Celsius to Fahrenheit.
To convert from degree Celsius (C) to degree Rankine (R), use the following formula:
A degree Celsius (°C) is one of the most common units for measuring temperature around the world. As a key part of the metric system, it's used in everything from daily weather forecasts to scientific research. It offers a straightforward and rational method for gauging the temperature of an object. The plural version is degrees Celsius.
The Celsius scale is cleverly based on the physical properties of water. This relationship to a familiar substance makes it very easy to understand. Let's break it down simply:
This perfect 100-degree interval between freezing and boiling is why it was initially called a "centigrade" scale (from "centi-" meaning 100). This straightforward system is the reason Celsius is the standard for temperature measurement in most countries.
In 1742, the Swedish astronomer Anders Celsius introduced his temperature scale, but with a surprising twist—it was upside down! He originally set 100° as the freezing point of water and 0° as its boiling point.
It was only after his death that the scale was flipped to the familiar version we use today, making it far more logical. This change is often credited to fellow scientist Carl Linnaeus.
Because Celsius is a global standard, knowing how to convert it to other scales, such as Fahrenheit (°F) and Kelvin (K), is useful. Here are the simple formulas to do it:
