Which unit categories are included?

Length, area, volume, mass, temperature, time, speed, acceleration, angles, data, force, pressure, energy, power, torque, frequency, and density are included.

Does temperature conversion use a different formula?

Yes. Temperature uses formulas rather than simple multiplication because Celsius, Fahrenheit, and Kelvin have different zero points.
