 * TRANSLATORS: This format string belongs to the macro used for

 *   - space if unit is not degree "°" (but this is not °C or °F!)
 *   - unit
 * Usually, you should leave this unchanged, BUT...
 * RTL TRANSLATORS: In case you did not translate the measurement
 * unit, use LRM (left-to-right mark) etc. to align it properly with
