Our free temperature converter instantly converts between Celsius (°C), Fahrenheit (°F), and Kelvin (K). Perfect for students, travelers, scientists, cooks, and anyone needing quick and accurate temperature conversions.
Using our temperature converter is effortless. Simply enter the temperature value in Celsius, and the tool automatically calculates and displays the equivalent values in both Fahrenheit and Kelvin. The conversions happen instantly as you type or adjust the value. You can also clear the input to start a new conversion. The tool uses precise mathematical formulas to ensure accuracy across all temperature scales.
Celsius (°C): Also known as centigrade, Celsius is the standard temperature scale in most countries worldwide. Water freezes at 0°C and boils at 100°C at standard atmospheric pressure. This scale is used in scientific contexts, weather forecasting, and everyday life in most nations except the United States.
Fahrenheit (°F): Primarily used in the United States, Fahrenheit sets water's freezing point at 32°F and boiling point at 212°F. This scale provides more granular measurements for everyday temperatures compared to Celsius. The formula to convert Celsius to Fahrenheit is: °F = (°C × 9/5) + 32.
Kelvin (K): The absolute temperature scale used in scientific research, Kelvin starts at absolute zero (-273.15°C), the theoretical temperature at which all molecular motion stops. Water freezes at 273.15 K and boils at 373.15 K. Kelvin is crucial in physics, chemistry, and astronomy. Note that Kelvin doesn't use the degree symbol.
Students use temperature converters for science homework and lab reports when working with different temperature scales. International travelers convert weather forecasts when visiting countries using different temperature scales. Cooks and bakers convert recipe temperatures when using cookbooks from different countries. Scientists and engineers convert between scales when reading research papers or collaborating internationally. HVAC technicians convert temperatures when working with equipment specifications. Medical professionals sometimes need conversions when using equipment calibrated in different scales. Weather enthusiasts convert forecasts to their preferred temperature scale.
Our tool uses these standard conversion formulas for accuracy:
• Celsius to Fahrenheit: °F = (°C × 9/5) + 32
• Celsius to Kelvin: K = °C + 273.15
• Fahrenheit to Celsius: °C = (°F - 32) × 5/9
• Kelvin to Celsius: °C = K - 273.15
These formulas are scientifically validated and provide accurate conversions for any temperature value you enter.
Understanding temperature references helps put conversions in context. Room temperature is approximately 20-22°C (68-72°F or 293-295 K). Body temperature is about 37°C (98.6°F or 310 K). A hot summer day might be 35°C (95°F or 308 K). Water freezes at 0°C (32°F or 273 K) and boils at 100°C (212°F or 373 K) at sea level. Absolute zero, the coldest possible temperature, is -273.15°C (-459.67°F or 0 K). These reference points help you quickly estimate conversions and understand temperature contexts.
All temperature conversions are calculated locally in your browser. No data is transmitted to servers, and the tool works offline. We use scientifically accurate conversion formulas to ensure precision in all calculations, suitable for both everyday use and scientific applications.
