The Formula

Unit conversion uses a fixed conversion factor between the two units. Multiply the input value by the factor to get the result. For temperature, the formula depends on the scales (e.g., °C to °F: multiply by 9/5 and add 32).

Worked Example

The weather forecast says it is 35°C outside. You want to know what that is in Fahrenheit. Using the formula °F = + 32, 35°C converts to 95°F. This converter handles Celsius, Fahrenheit, and Kelvin instantly.

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
