Kelvin Temperature Conversion Formulas

$$\text{Celsius (°C)} = K – 273.15$$ $$\text{Fahrenheit (°F)} = (K – 273.15) \times 1.8 + 32$$ $$\text{Rankine (°R)} = K \times 1.8$$ $$\text{Newton (°N)} = \frac{K – 273.15}{3.03030303}$$ $$\text{Delisle (°De)} = (373.15 – K) \times \frac{3}{2}$$ $$\text{Reaumur (°Re)} = (K – 273.15) \times 0.8$$ $$\text{Rømer (°Rø)} = \left( \frac{K – 273.15}{1.9047619} \right) + 7.5$$

Kelvin is the SI base unit for temperature, widely used in thermodynamics and scientific research. These formulas allow accurate conversions to other scales for broader application and comparison.

Kelvin is the absolute temperature scale used in physics and chemistry. This converter makes it easy to switch from Kelvin to Celsius for general use, to Fahrenheit for weather and U.S.-based applications, and to historical or alternative scales like Delisle or Rømer. Designed for students, researchers, and professionals, it bridges the gap between scientific and practical temperature measurements.
