What categories of units are supported?
The tool converts temperature, length, weight, volume, and speed between all common units in each category.
How is temperature conversion different from other conversions?
Most unit conversions use simple multiplication. Temperature conversions (Celsius, Fahrenheit, Kelvin) require both multiplication and addition because the scales have different zero points.
