About Temperature Conversions
Temperature scales are uniquely challenging because they involve non-linear conversions with different zero points. Unlike length or weight, you cannot simply multiply by a factor — converting 0°C to Fahrenheit requires both multiplication and addition (0°C × 9/5 + 32 = 32°F). The Celsius and Fahrenheit scales intersect at exactly -40°, a useful fact for quick mental verification. For scientific work, the Kelvin scale starts at absolute zero (-273.15°C) and is essential in thermodynamics, gas law calculations, and astrophysics. Our converter implements exact conversion formulas for all seven supported temperature scales, including the historical Delisle, Newton, and Réaumur scales still referenced in scientific literature.
| Unit Name | Symbol | Value | Formula |
|---|---|---|---|
| Celsius | °C | 1 | base unit |
| Delisle | °De | 148.5 | °C = 100 − °De × 2/3 |
| Fahrenheit | °F | 33.8 | °C = (°F − 32) × 5/9 |
| Kelvin | K | 274.15 | °C = K − 273.15 |
| Newton | °N | 0.33 | °C = °N × 100/33 |
| Rankine | °R | 493.47 | °C = (°R − 491.67) × 5/9 |
| Réaumur | °Ré | 0.8 | °C = °Ré / 0.8 |
