To convert Celsius to Fahrenheit, use the formula: °F = (°C × 9/5) + 32. For example, 25°C = (25 × 9/5) + 32 = 77°F. Our temperature converter does this calculation instantly.
Absolute zero is the lowest possible temperature where all molecular motion stops. It equals 0 Kelvin, -273.15°C, -459.67°F, and 0 Rankine.
To convert Fahrenheit to Celsius, use the formula: °C = (°F - 32) × 5/9. For example, 98.6°F = (98.6 - 32) × 5/9 = 37°C (normal body temperature).
The Kelvin scale is primarily used in scientific contexts. It starts at absolute zero and uses the same increment size as Celsius. To convert Celsius to Kelvin, add 273.15. For example, 25°C = 298.15 K.
Celsius and Fahrenheit are equal at -40 degrees. This is the only temperature where both scales show the same value: -40°C = -40°F.
