Understanding Temperature 🌡️
Temperature measures the warmth or coldness of a substance, environment, or system.
This converter allows switching between Celsius, Fahrenheit, Kelvin, and Rankine, covering everyday weather, cooking, scientific experiments, and engineering calculations.
Key Facts
- Celsius (°C) is standard metric, used worldwide for weather, cooking, and science.
- Fahrenheit (°F) is common in the US for household and weather readings.
- Kelvin (K) is the absolute scale used in physics and engineering; 0 K = absolute zero.
- Rankine (°R) is an absolute Fahrenheit-based scale used in thermodynamics and US engineering.
Formulas
°F = (°C × 9/5) + 32- Convert Celsius to Fahrenheit.°C = (°F − 32) × 5/9- Convert Fahrenheit to Celsius.K = °C + 273.15- Convert Celsius to Kelvin.°C = K − 273.15- Convert Kelvin to Celsius.°R = °F + 459.67- Convert Fahrenheit to Rankine.°F = °R − 459.67- Convert Rankine to Fahrenheit.
Temperature Conversion Examples
- Room temperature: 20°C ≈ 68°F ≈ 293 K ≈ 527°R
- Boiling water: 100°C ≈ 212°F ≈ 373 K ≈ 671°R
- Freezing water: 0°C ≈ 32°F ≈ 273 K ≈ 491°R
- Absolute zero: 0 K ≈ -273.15°C ≈ -459.67°F ≈ 0°R
FAQs
