Free Online Unit Conversion Tools
Single-pair converters, mostly: Celsius to Fahrenheit, kilometers to miles, kilograms to pounds, liters, square meters, megabytes. Keeping them separate means you land on the one you searched for instead of hunting through a dropdown of ninety units. The data-size ones are where the ambiguity lives, since a kilobyte means 1,000 bytes in storage marketing and 1,024 in a lot of software.
