Understanding Celsius and Kelvin 🧪
Kelvin is the absolute temperature scale widely used in science and engineering.
Converting between Celsius and Kelvin is essential for physics, chemistry, and thermodynamics where absolute temperature is required.
Key Facts
- Celsius (°C) is relative, while Kelvin (K) starts at absolute zero.
- Kelvin values are always positive.
- 1 K = 1°C in scale increments, just offset by 273.15.
Formulas
K = °C + 273.15- Convert Celsius to Kelvin.°C = K − 273.15- Convert Kelvin to Celsius.
Celsius ↔ Kelvin Examples
- Freezing water: 0°C ≈ 273 K
- Room temperature: 20°C ≈ 293 K
- Boiling water: 100°C ≈ 373 K
- Very cold day: -20°C ≈ 253 K
FAQs
Why use Kelvin instead of Celsius?
Kelvin is needed for scientific and engineering calculations where absolute temperature is important, such as thermodynamics.
Can Kelvin be negative?
No, Kelvin starts at absolute zero (0 K), the lowest possible temperature.
How do I quickly convert Celsius to Kelvin?
Simply add 273.15 to the Celsius value.
