About Temperature Conversion

Temperature is a key parameter in chemical engineering. The most common units are Celsius (°C), Fahrenheit (°F), and Kelvin (K). This converter applies the exact formulas:

°C → °F: F = (C × 9/5) + 32
°F → °C: C = (F − 32) × 5/9
°C → K: K = C + 273.15
K → °C: C = K − 273.15
°F → K: K = (F − 32) × 5/9 + 273.15
K → °F: F = (K − 273.15) × 9/5 + 32

By selecting the input and output units, you can easily switch between scales used in different industries and academic references.

FAQs

Q: What is the SI unit of temperature?
A: Kelvin (K).

Q: Why is 273.15 added when converting °C to K?
A: Because 0 K (absolute zero) = −273.15 °C.

Q: Which industries still use Fahrenheit?
A: Fahrenheit is widely used in the USA, especially in HVAC and meteorology.
