Understanding unit conversion
Unit conversion changes a measurement from one unit into another equivalent unit. For many categories, the converter uses a common base unit and applies the appropriate conversion factor. Temperature is different because Celsius, Fahrenheit, and Kelvin use different zero points, so temperature conversion requires both scaling and an offset.
Results are formatted for readability. Very large or very small values may be displayed using scientific notation, while ordinary values are shown with a practical number of decimal places.
