Pick a category, choose the two units, type a value — it converts as you go. Press Run to add it to the list.

Why is temperature handled differently?

Temperature isn't a simple multiple — 0 °C isn't 0 °F — so a fixed formula is used instead.

Press the ⇄ button between the two unit pickers.

Choose 2, 4, 6 or 8 decimal places, and turn on scientific notation to see it as an exponent — 1.23e+4, for instance.
