What is a Temperature Converter?
A temperature converter is a tool that converts temperature measurements from one scale to another. Whether you need to convert Celsius to Fahrenheit, Fahrenheit to Kelvin, or any combination, a temperature converter makes these calculations instant and accurate.
Temperature conversions are essential in many fields including weather, cooking, science, engineering, medicine, and everyday life. Different countries and scientific disciplines use different temperature scales, making conversions a common necessity.
Our temperature converter supports three main temperature scales: Celsius (°C), Fahrenheit (°F), and Kelvin (K). Each scale has its own use cases and reference points, making conversions between them essential for international communication and scientific work.
How it Works
Temperature conversions are different from other unit conversions because temperature scales don't share a common zero point. This means conversion involves both multiplication and addition/subtraction:
Celsius to Fahrenheit
Example: 0°C = 32°F (freezing point of water), 100°C = 212°F (boiling point of water)
Fahrenheit to Celsius
Example: 32°F = 0°C, 212°F = 100°C
Celsius to Kelvin
Example: 0°C = 273.15 K, 100°C = 373.15 K
Our converter automatically handles all these conversions, giving you instant results as you enter temperature values. Simply select your source and target scales, enter the temperature, and get the converted value.
Supported Units
Celsius (°C)
The metric temperature scale used in most of the world. Water freezes at 0°C and boils at 100°C at standard atmospheric pressure.
Used in: Most countries, scientific research, weather reports
Fahrenheit (°F)
The imperial temperature scale used primarily in the United States. Water freezes at 32°F and boils at 212°F at standard atmospheric pressure.
Used in: United States, some Caribbean countries, weather reports
Kelvin (K)
The absolute temperature scale used in scientific work. Absolute zero (0 K) is the theoretical lowest possible temperature. No negative values.
Used in: Physics, chemistry, scientific research, thermodynamics
Common Use Cases
- Weather: Convert temperature readings between Celsius and Fahrenheit when traveling or reading international weather reports
- Cooking: Convert oven temperatures and recipe temperatures between Celsius and Fahrenheit
- Science & Research: Convert between Celsius and Kelvin for scientific calculations and experiments
- Medicine: Convert body temperature readings between different scales
- Engineering: Convert temperature specifications and operating ranges for equipment and systems
- Education: Help students understand different temperature scales and practice conversions
- International Communication: Convert temperatures when communicating with people using different measurement systems
Conversion Examples
Body Temperature
Normal body temperature: 98.6°F = 37°C = 310.15 K
This is the standard human body temperature, commonly used in medical contexts.
Freezing Point of Water
0°C = 32°F = 273.15 K
The temperature at which water freezes at standard atmospheric pressure. This is a key reference point for all three scales.
Boiling Point of Water
100°C = 212°F = 373.15 K
The temperature at which water boils at standard atmospheric pressure. Another key reference point for temperature scales.
Room Temperature
20°C = 68°F = 293.15 K
A typical comfortable room temperature, often used as a reference in various contexts.
Frequently Asked Questions
Temperature scales don't share a common zero point. For example, 0°C equals 32°F, not 0°F. This means conversion involves both multiplication (to adjust the scale) and addition/subtraction (to adjust the zero point), unlike simple unit conversions that only require multiplication.
Absolute zero is 0 Kelvin (-273.15°C or -459.67°F), the theoretical lowest possible temperature where all molecular motion stops. It's the reference point for the Kelvin scale and cannot be reached in practice, though scientists have come very close.
Kelvin is an absolute scale (starting at absolute zero), so it doesn't use the degree symbol. It's simply written as "K" (e.g., 273.15 K), not "°K". This is the official international standard.
