Temperature Converters
Temperature Scales and Thermal Conversion Tools
Convert temperature readings instantly between everyday weather units, culinary oven settings, and scientific thermodynamic scales. Unlike linear metrics, temperature conversions incorporate scale offsets.
Supported Temperature Scales
- Degrees Celsius (°C): Standard SI-derived metric temperature scale.
- Degrees Fahrenheit (°F): Customary US temperature scale.
- Kelvin (K): SI base unit of thermodynamic temperature starting at absolute zero.
Temperature Conversion Quick Formulas
| Conversion Direction | Mathematical Formula | Common Real-World Reference |
|---|---|---|
| Celsius to Fahrenheit | °F = (°C × 9/5) + 32 | 0°C = 32°F (Freezing point of water) |
| Fahrenheit to Celsius | °C = (°F − 32) × 5/9 | 212°F = 100°C (Boiling point of water) |
| Celsius to Kelvin | K = °C + 273.15 | 25°C = 298.15 K (Standard laboratory temp) |
| Kelvin to Celsius | °C = K − 273.15 | 0 K = -273.15°C (Absolute zero) |
Frequently Asked Questions
At what temperature are Celsius and Fahrenheit identical?
Celsius and Fahrenheit intersect at exactly -40 degrees (-40°C = -40°F).
Why does the Kelvin scale not use a degree symbol?
Kelvin is an absolute thermodynamic unit, not an arbitrary interval scale, so it is written simply as K, not °K.
