Celsius Temperature Conversion Formulas

Formula
$$\begin{align*} \text{Fahrenheit (°F)} &= (\text{°C} \times 1.8) + 32 \\ \text{Kelvin (K)} &= \text{°C} + 273.15 \\ \text{Rankine (°R)} &= (\text{°C} \times 1.8) + 491.67 \\ \text{Newton (°N)} &= \frac{\text{°C}}{3.03030303} \\ \text{Delisle (°De)} &= (100 – \text{°C}) \times \frac{3}{2} \\ \text{Reaumur (°Re)} &= \text{°C} \times 0.8 \\ \text{Rømer (°Rø)} &= \left( \frac{\text{°C}}{1.9047619} \right) + 7.5 \end{align*}$$

These formulas convert Celsius to various temperature scales used in scientific and historical contexts. They are useful for comparing results across systems or working with global scientific data.

Temperature conversions are essential in chemistry, physics, and environmental science. Whether you’re working in a lab or converting weather reports, this calculator simplifies the process by supporting both modern (Kelvin, Fahrenheit) and historical (Delisle, Newton, Rømer) temperature scales. All conversions are based on exact scientific formulas, ensuring precise results.
