Common unit converters
Unit conversion is the process of converting a quantity expressed in one unit to another. This is done with conversion factors—multipliers that express the relationship between the original unit and the desired unit. For example, you can use a conversion factor to convert a volume measurement in gallons to liters or vice versa.
