How do I convert Celsius to Fahrenheit (C to F)?

To convert temperature from Celsius (°C) to Fahrenheit (°F), you use the formula: F = (C * 9/5) + 32. For example, 20°C is equal to 68°F.

How do I convert Fahrenheit to Celsius (F to C)?

To convert temperature from Fahrenheit (°F) to Celsius (°C), you use the formula: C = (F - 32) * 5/9. For example, 68°F is equal to 20°C.

Kelvin (K) is the base unit of temperature in the International System of Units (SI). It's used in science and engineering. 0°C (the freezing point of water) is 273.15 K. Absolute zero (the coldest possible temperature) is 0 K.
