How to convert Celsius to Fahrenheit
Multiply the temperature in Celsius by 9/5 and add 32: °F = °C × 9/5 + 32. For example, 20 °C × 9/5 + 32 = 68 °F. Temperature is not a simple ratio because the two scales start at different zero points, so you must add the 32.
Where you will use it
Celsius-to-Fahrenheit is a daily need across systems: reading a weather forecast, setting an oven from a metric recipe, or checking a body temperature stated in Celsius against Fahrenheit ranges.
