🌡️ Temperature Converter
Enter a temperature in Celsius, Fahrenheit, or Kelvin and instantly see it in all three scales — the quick way to read any weather forecast or heat advisory, wherever you are.
🔁 One Value, Three Scales
What is a Temperature Converter?
It turns a single temperature reading into all three common scales — Celsius, Fahrenheit, and Kelvin — in one step. Enter the value and pick its scale, and the converter normalises it and shows the equivalents, so a forecast in one system instantly makes sense in the one you think in.
Use it to read a heatwave advisory from another country, follow a recipe or a science lesson, or settle the perennial “how hot is that in real terms?” question. The conversions are exact arithmetic, rounded to two decimals for readability.
❓ Frequently Asked Questions
How do I convert Celsius to Fahrenheit?
Multiply the Celsius value by 9/5 and add 32. For example, 30°C × 9/5 = 54, plus 32 = 86°F. To go the other way, subtract 32 from the Fahrenheit value and multiply by 5/9. This tool does the arithmetic for you and shows the result in all three scales at once.
What is Kelvin, and when would I use it?
Kelvin is the SI base unit of temperature, used in science and engineering. It starts at absolute zero — the coldest anything can be — which is −273.15°C or −459.67°F. A change of one kelvin equals a change of one degree Celsius, so to convert you simply add 273.15 to the Celsius value.
What are some useful temperature reference points?
Water freezes at 0°C (32°F, 273.15 K) and boils at 100°C (212°F, 373.15 K) at sea level. Normal human body temperature is about 37°C (98.6°F). A hot summer day of 35°C is 95°F, and a scorching 40°C heatwave is a sweltering 104°F.
Why does knowing both scales matter in the heat?
Weather forecasts, heat-index charts, and safety guidance use different scales in different countries — much of the world reports temperatures in Celsius, while the United States uses Fahrenheit. Being able to convert quickly helps you read any forecast, compare a heat advisory to what you're used to, and judge how hot it really is wherever you are.
