How to Convert Units
Published Apr 17, 2026
Unit conversion is the process of expressing a measurement in a different unit of the same quantity. The general method is:
result = value × (from_factor / to_factor)
Where each factor represents how many base units (e.g. meters, grams, litres) one unit equals.

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