Measure that comes into force! (4)
I believe the answer is:
dyne
This might be a double definition.
'measure that comes' is the first definition.
'dyne' can be an answer for 'measure' (dyne is a kind of measure). I'm not certain of the remainder of the definition.
'force' is the second definition.
(I've seen this before)
'into' is the link.
Can you help me to learn more?
(Other definitions for dyne that I've seen before include "Unit of force" , "physics unit" .)
