Steve,

A degree ampere? A degree meter? Methinks not!

The SI unit of temperature is the kelvin, symbol K and there is a derived unit called degree Celsius, symbol °C which has the same magnitude. That's all there is to it.

In the example you give I think it should be made clear in text that the figure is a differential specification rather than relying on the equivocal 'degree'. This is after all how it is done with every other physical unit.


Best regards,
Rob.
