As a physicist I don't like any value without units. The degree symbol is
not needed, but C would be great: 21 C, 70 F.

Not instantly, it's a popular hobby in some countries to swim
in a hole in the ice. Look up:

Agree.
If you are using a virtual keyboard on a touch-screen device, there is usually
one or more panels of punctuation characters, including the degree symbol.
Incidentally, this is a straw poll (nonbinding vote), not a straw pole (a
bundle of straw serving as a pole).

This is my clear favourite.

technical problem with the units: Celsius °C and °F have the degree

C'mon folks. Temperatures are always measured in degrees, hence it is
completely unnecessary to include this hard-to-type symbol in the value. We
know if it's a temperature, the value will be a certain number of degrees.
As for regional differences, let's not go there. The metric system is the
There is no regional default if the units are not specified.
In the case of maxspeed it is always km/h if the units are not specified.
If mph is intended then mph must be specified.

So, for your example of temperature, if the units are not

I have not come across a precedent for region-dependent default units.
The wiki pages for Units and maxspeed seem to be quite clear that the
default unit is km/h. If they are to be region-dependent we will also
need a default default, if you are outside of any region with a defined
How it's entered into the database, and how it's displayed, are two
separate things. Humans are messy. Unless the API starts validating
entries, entries will vary in format, even if we officially say that 46 C
is the official format. But software can parse and normalize numbers.
That said:
I think that, as for elevations, it should default to degrees Celsius. That
is, taking the number 20 as a value would mean 20 degrees C. The tag could
accept Fahrenheit if the numeric value is followed by a space and the
letter F.
Also, no degree symbols please.

I think if no unit is specified then it should be taken to mean Celsius
worldwide. To define the unit explicitly use n[.n][C|F]. We should also
state that the degree symbol is not required (and maybe that it should
never be present).
At least, that's my opinion.
