Space between value and unit #7455
Description
Currently, Angle.to_string doesn't include a space between the value and unit:
In [30]: from astropy.coordinates import Angle
In [31]: a = Angle(3, 'deg')
In [32]: a.to_string(unit='mas')
Out[32]: '1.08e+07mas'I think there are cases where it would make sense to allow a space to be included, so this is a feature request to add a boolean keyword argument to optionally add a space.
Note that Quantity does include a space by default so maybe actually we should just change the default and not add an option?
In [17]: str(3 * u.mas)
Out[17]: '3.0 mas'

isn't it good form to always have a space between the value and the unit?

👍 for consistency between Quantity and Angle (by having space as default).
However, if you worry about backward compatibility, maybe instead add an option for "old style" (without space), but would that be useful for anyone?

Well the one place where we don't want a space is when using a symbol, e.g.
3.4"pllim commentedon May 11, 2018

@astrofrog I think we should use a space by default (probably the most common use case), and then add a boolean keyword argument to optionally not include a space (e.g.
3.4").astrofrog commentedon Jun 20, 2018
I agree!
