There was a program on the Science Channel a few days ago dealing with
the possibility (or impossibility) of terraforming Mars. The
commentator said that one effect being discussed could raise the
temperature on Mars by as much as 20°C or 68°F.
Dual unit confusion once more.

4 °C is 39.2 °F but a change in
temperature of 4 °C is 7.2 °F.
It should be 39.2 F

In a story about the effects of global
warming in Australia at CNN.com, we can see where using duel units
leads to errors:
"...But emissions would still increase
over today's levels, with some environmental groups calculating a 100
percent rise by 2050, resulting in a temperature increase of 4 C (5 F).
..."
Since Australia is metric, we can take
the metric temperature as authoritative. In which case, the conversion
should be 7 F
