The change to lowercase is correct, but I'm not convinced by the removal
of the space. The SI says that there should be a space, and while there
are some cases where readability is considerably improved by removing
the space, I think this is not one of those.
See the SI draft (2006):
5.3.3 Formatting the value of a quantity
The numerical value always precedes the unit, and a space
is always used to separate the unit from the number.
Thus the value of the quantity is the product of the num‐
ber and the unit, the space being regarded as a multipli‐
cation sign (just as a space between units implies multi‐
plication). The only exceptions to this rule are for the
unit symbols for degree, minute, and second for plane an‐
gle, °, ′, and ′′, respectively, for which no space is
left between the numerical value and the unit symbol.
This rule means that the symbol °C for the degree Celsius
is preceded by a space when one expresses values of Cel‐
sius temperature t.
Even when the value of a quantity is used as an adjec‐
tive, a space is left between the numerical value and the
unit symbol. Only when the name of the unit is spelled
out would the ordinary rules of grammar apply, so that in
English a hyphen would be used to separate the number
from the unit.
In any one expression, only one unit is used. An excep‐
tion to this rule is in expressing the values of time and
of plane angles using non-SI units. However, for plane
angles it is generally preferable to divide the degree
decimally. Thus one would write 22.20° rather than 22°
12′, except in fields such as navigation, cartography,
astronomy, and in the measurement of very small angles.
