Three scales dominate: Celsius (worldwide), Fahrenheit (US), and Kelvin (science). Understanding conversion is essential for cooking, science, and travel.
The Three Scales
Celsius: 0°=freeze, 100°=boil. Fahrenheit: 32°=freeze, 212°=boil. Kelvin: starts at absolute zero (−273.15°C).
Absolute Zero
0 K (−273.15°C) is the theoretical lowest temperature. Kelvin is used in physics because it has no negative values.

Applications
Converting Temperatures for Cooking
When cooking, it's important to use the correct temperature range for the type of dish you are preparing. For example, if you are making a cake, you will want to use a temperature range of 350°F to 400°F (175°C to 200°C), while cooking a steak may require a temperature range of 300°F to 450°F (150°C to 230°C). Our temperature converter tool can help you convert temperatures accurately for your specific recipe.
Examples of Temperature Conversion
For example, if you want to convert 20°C to Fahrenheit, you would enter 20 in the input field and select Fahrenheit as the desired unit. The tool will then display the temperature in Fahrenheit, which is 68°F.
Converting Temperatures for Scientific Applications
The temperature converter tool can be used to convert temperatures between different units of measurement for scientific applications, such as meteorology, climatology, and thermodynamics. For example, you can use the tool to convert temperatures from Celsius to Fahrenheit for a specific date and time to determine the corresponding temperature in the US customary unit of measurement.
Examples of temperature conversion using the converter tool
For example, you can use the converter tool to convert 20°C to Fahrenheit, which would give you a temperature of 68°F. Or, you can use it to convert 0°K to Celsius, which would give you a temperature of 32°C.
Frequently Asked Questions
How do you convert °C to °F?
Multiply by 9/5 then add 32. For example, 25°C × 9/5 + 32 = 77°F.
What temperature is the same in °C and °F?
−40°C = −40°F. The only point where both scales intersect.
Why does the US use Fahrenheit?
Historical momentum from British colonial influence. Never switched to Celsius.
Can I convert temperatures between different units of measurement using the converter tool?
Yes, our temperature converter tool allows you to convert temperatures between Celsius, Fahrenheit, and Kelvin.
How do I know if a temperature is positive or negative in Celsius?
In Celsius, a positive temperature is above 0°C, while a negative temperature is below 0°C. For example, 10°C is a positive temperature, while -5°C is a negative temperature.
How do I convert temperatures between different units of measurement using the converter tool?
The temperature converter tool allows you to convert temperatures between Celsius, Fahrenheit, and Kelvin. Simply enter the temperature in one unit of measurement and select the desired unit for the conversion.
How do I convert temperatures between Celsius and Kelvin?
To convert a temperature from Celsius to Kelvin, subtract 273.15. For example, 20°C is equal to 293.15 K.
Can I use the converter tool to convert temperatures between different units of measurement for a specific date and time?
Yes, you can use the converter tool to convert temperatures for a specific date and time by selecting those parameters when using the tool.
