Solved clues about current small scale (7)
I believe the answer is:
celsius
'scale' is the definition.
(I have seen 'Scale of temperature ' mean 'celsius' so perhaps 'scale' could also mean 'celsius')
'solved clues about current small' is the wordplay.
'solved' indicates anagramming the letters (the anagram must be solved).
'about' is a charade indicator (letters next to each other).
'current' becomes 'I' (symbol for electric current).
'small' becomes 's' (abbreviation - e.g. clothes size).
'clues' after 'i' is 'iclues'.
'iclues' is an anagram of 'celsiu'.
'celsiu'+'s'='CELSIUS'
(Other definitions for celsius that I've seen before include "Scale of temperature devised by Swiss astronomer" , "Scale of temperature devised by Swedish astronomer" , "Man responsible for scale" , "Swedish astronomer, deviser of the centigrade thermometer" , "Freezing point is 0 degrees on this scale" .)
