PE Lines numbering

We often see this on PE line packaging and on some rods and reels, e.g. PE 1~3, PE 3~6 (rods) or PE 1/200m, PE 2.5/200m , PE 5/300m (reels).... and so on.
So, what it mean?

Also, we may see these numbering on mono line packaging too. e.g. No. 2, No. 7 etc... On reels, No. 2/ 127m, No.3/110, No. 5/120m.... etc...
What it mean?

Of cause, many of you know.
But there are a handful of fellow anglers out there may still get very much mixed up by these numbering.

Below table was extracted from Necroplastic, which will explain the relationship of PE number to its thickness and strength.

PE No..mm
0.6...0.128
0.8...0.148
1.0...0.165
1.2...0.185
1.5...0.205
1.7...0.218
2.0...0.235
2.5...0.260
3.0...0.285
3.5...0.310
4.0...0.330
5.0...0.370
6.0...0.405
7.0...0.435
8.0...0.470
10.0...0.520
12.0...0.570
14.0...0.620
16.0...0.660
18.0...0.700
20.0...0.740
22.0...0.780
24.0...0.810
28.0...0.870

This form of measurement is a very accurate and standardized form and is especially used in relation to Japanese reels. The normal line thickness to line poundage would be 10lbs/PE or easily said, PE number X 10lbs; PE 5 = 50lbs. However, with the technological advancements nowadays, manufacturers have been able to produce thinner, stronger lines.

As for Mono numbering, similar to the PE's, indicate its standard diameter/thickness.

I do not have the table, but on the whole, every number approximately equal to 4Lbs.
As such, No1 about 4Lbs, No. 2 about 8Lbs, No. 2.5 about 10Lbs, No. 10 about 40Lbs and so on...

The rated strength of the mono varies a little among different manufacturers and brands. But basing on every 1 number equal to 4 Lbs is very safe.

Good fishing
