Classic reference.
There are fourteen categories: length, mass, temperature, data, time, speed, area, pressure, volume, energy, power, angle, frequency and fuel economy. Each one holds several units, from nanometer to nautical mile, from bit to exbibyte, from pascal to atmosphere, and conversion only happens between units of the same kind, because turning meters into seconds makes no sense.

Yes. The unit converter also lets you run the conversion in the opposite direction when needed.
