Convert between all 8 temperature scales with full precision
| Point | °C | °F | K |

A temperature converter is a simple online tool that takes a temperature value in one unit and automatically calculates its equivalent in other units. Instead of manually applying conversion formulas, you just enter a number, and the tool does the math for you — accurately and instantly.
Our converter supports the three most widely used temperature scales: Celsius (°C), Fahrenheit (°F), and Kelvin (K).
Celsius (°C)
Celsius is the most commonly used temperature scale in the world. It’s the standard for everyday weather, cooking, and science in most countries. Water freezes at 0°C and boils at 100°C at sea level.
Fahrenheit (°F)
Fahrenheit is primarily used in the United States. Body temperature is around 98.6°F, water freezes at 32°F, and boils at 212°F. If you’re traveling to or from the US, knowing how to convert Fahrenheit to Celsius — and back — is genuinely useful.
Kelvin (K)
Kelvin is the scientific standard used in physics, chemistry, and engineering. It starts at absolute zero — the coldest theoretically possible temperature — which equals −273.15°C or −459.67°F. Kelvin has no negative values, making it ideal for scientific calculations.
Using this tool is straightforward. Enter your temperature value in the input field, select the unit you’re converting from, and the converter instantly displays the equivalent values in all other supported units. No button to click, no page reload — just instant results as you type.
For those who prefer to understand the math behind the conversions, here are the standard formulas:
Our converter applies these exact formulas under the hood, so you always get precise, reliable results without having to remember a single one of them.
Understanding a few key reference points can make temperature scales more intuitive in daily life.
Absolute zero sits at −273.15°C, −459.67°F, and 0 K — the lowest theoretically possible temperature where all molecular motion stops.
Water freezes at 0°C, 32°F, and 273.15 K.
Normal human body temperature is around 37°C, 98.6°F, and 310.15 K.
Water boils at 100°C, 212°F, and 373.15 K.
Temperature converters are helpful for a wide range of people. Students use them to solve physics and chemistry problems. Travelers rely on them to understand local weather forecasts. Home cooks and bakers often need to convert oven temperatures between recipes from different countries. Scientists and engineers work with Kelvin regularly. Anyone who encounters temperatures across different unit systems benefits from a fast, reliable converter.

Celsius and Fahrenheit are both temperature scales, but they use different reference points and intervals. Celsius is based on the freezing and boiling points of water (0°C and 100°C), while Fahrenheit uses 32°F and 212°F for the same points. The two scales cross at −40 degrees, where both read the same value.
Absolute zero is the lowest possible temperature. It equals −273.15°C, −459.67°F, and exactly 0 K. At this temperature, particles have minimum thermal motion.
Yes, completely free. There’s no account needed, no download, and no usage limit. Just open the tool and start converting.
Absolutely. The converter handles negative values without any issue, which is useful for temperatures below freezing or for working with Kelvin near absolute zero.
