Measure used by the tiler? (5)

I believe the answer is:

litre

I'm a little stuck... Click here to teach me more about this clue!

'measure' is the definition.
(litre is a kind of measure)

'by the tiler' is the wordplay.
'tiler' can be anagrammed to 'LITRE'.
Though, I am not sure how this is indicated.

'used' is the link.

Can you help me to learn more?

(Other definitions for litre that I've seen before include "Metric measure of capacity" , "Metric unit of volume" , "Unit of capacity in metric system" , "1.7598 UK pints" , "less than two pints" .)

I've seen this clue in the Evening Standard.
