Indeed, but if you use mathematical annotation you wil have more 
control. See ?plotmath for details.

Some examples:

plot(1:10, main =
     substitute(tm2 * degree * "C, " * p2 * "mm",
         list(tm2 = round(mean(tm*10))/10, p2 = round(sum(p)))))


plot(1:10, main =
     substitute(tm2 * degree ~~ "C, " * p2 * "mm",
         list(tm2 = round(mean(tm*10))/10, p2 = round(sum(p)))))

plot(1:10, main =
     substitute(tm2 * degree * phantom(".") * "C, " * p2 * "mm",
         list(tm2 = round(mean(tm*10))/10, p2 = round(sum(p)))))

plot(1:10, main =
     substitute(tm2 * degree * phantom("m") * "C, " * p2 * "mm",
         list(tm2 = round(mean(tm*10))/10, p2 = round(sum(p)))))
