Strimmer Line
What does a metre cost?
Add the pack price and any known delivery charge, then divide by the stated line length in metres. For a 15-metre pack, the divisor is 15. Compare packs of the same diameter and profile.
The result is a price per metre, not a measure of cutting performance. It cannot tell you how much your spool holds or how long the line will last. Those questions need the machine instructions and, where available, suitable test evidence.
