About Temperature Conversion

Temperature is measured differently around the world. The Celsius scale is the most widely used internationally, while Fahrenheit is primarily used in the United States for everyday temperatures. Scientists worldwide use Kelvin as the absolute temperature scale. Rankine is used in engineering applications, particularly in the United States.

Unlike other unit conversions that are simple multiplication, temperature conversions require both multiplication and addition, making them easy to get wrong without a reliable converter.

Temperature Conversion Formulas

• Celsius to Fahrenheit: °F = (°C × 9/5) + 32
• Fahrenheit to Celsius: °C = (°F - 32) × 5/9
• Celsius to Kelvin: K = °C + 273.15
• Kelvin to Celsius: °C = K - 273.15
• Celsius to Rankine: °R = (°C + 273.15) × 9/5
