Temperature Converter
Temperature measurement differs across regions and scientific fields. While the United States relies on the Fahrenheit scale for weather and cooking, most of the globe uses Celsius, and scientists use thermodynamic Kelvin.
Common Temperature Converter Conversions
| Unit Standard | Target Equivalent | Formula | Practical Example |
|---|---|---|---|
| 0 °C (Freezing point of water) | 32 °F / 273.15 K | (0 × 9/5) + 32 | 0 °C = 32 °F |
| 100 °C (Boiling point of water) | 212 °F / 373.15 K | (100 × 9/5) + 32 | 100 °C = 212 °F |
| 37 °C (Normal body temp) | 98.6 °F | (37 × 9/5) + 32 | 37 °C = 98.6 °F |
| -40 °C | -40 °F | Identical point on both scales | -40 °C = -40 °F |
How Temperature Converter Math Works
Unlike units with zero at the origin, temperature scales use offsets. Fahrenheit to Celsius: (°F − 32) × 5/9 = °C. Celsius to Fahrenheit: (°C × 9/5) + 32 = °F. Celsius to Kelvin: °C + 273.15 = K.
Frequently Asked Questions
At what temperature are Celsius and Fahrenheit equal?
Celsius and Fahrenheit read the exact same value at -40 degrees (-40 °C = -40 °F).
What is absolute zero?
Absolute zero is 0 Kelvin, which equals -273.15 °C or -459.67 °F. At this temperature, thermodynamic entropy reaches its minimum.
