Temperature Conversion: How to Easily Convert Celsius to Fahrenheit and Vice Versa

At some point, we've all had to deal with temperature conversion—whether you're cooking, traveling, or working in science. Maybe you're adjusting your oven or checking the weather in another country. Knowing how to convert between Celsius, Fahrenheit, and Kelvin is super important. This guide will break down the basics of temperature conversion and give you everything you need to convert these scales without stress.

Temperature conversion is something most of us do without even thinking about it. Whether you're cooking a new recipe, checking the weather in a foreign country, or working with scientific data, knowing how to convert between Celsius, Fahrenheit, and Kelvin is key.

• Celsius (°C) is the most common temperature scale around the world, except in the U.S., where Fahrenheit (°F) is used. Fahrenheit is based on the freezing and boiling points of water—32°F and 212°F, respectively.
• Kelvin (K) is used in science and represents the absolute temperature scale, starting at absolute zero (the point where all molecular motion stops), which is -273.15°C or -459.67°F.

Being able to convert between these temperature units is helpful in many situations. The good news? There are simple formulas and online tools that make these conversions super easy.

In this guide, we'll show you how to convert between Celsius, Fahrenheit, and Kelvin step by step. Plus, we’ll introduce some handy online converters to help you get the job done quickly.
