PE ↔ lb Line Conversion
PE (polyethylene) ratings are how Japanese tackle brands describe braided line. The PE number measures diameter, not breaking strength — so the lb-test equivalent depends on the braid manufacturer's specific weave and material. The calculator below uses typical mid-grade conversions.
PE ratings vary by braid manufacturer — values shown are typical mid-grade equivalents. Check the spool label for your specific brand's calibration.
| PE rating | Typical lb test | Typical use |
|---|---|---|
| PE 0.3 | 6 lb | Ajing, mebaru, micro finesse |
| PE 0.5 | 10 lb | Trout, light finesse, eging |
| PE 0.8 | 16 lb | Bass finesse, sea bass, light inshore |
| PE 1.0 | 20 lb | All-around bass casting, light saltwater |
| PE 1.5 | 30 lb | Heavy bass cover, medium inshore |
| PE 2.0 | 40 lb | Saltwater shore, snook, redfish |
| PE 3.0 | 60 lb | Jigging, popping, larger inshore |
| PE 5.0 | 100 lb | Offshore jigging, GT, tuna, large pelagics |
| PE 8.0 | 150 lb | Big-game offshore, slow-pitch jigging |
Lure Weight: Ounces ↔ Grams
US tackle is rated in fractional ounces; most Japanese and European lures are rated in grams. Convert below, or use the common-fractions shortcut for typical lure weights.
| Ounces | Grams | Typical lure |
|---|---|---|
| 1/32 | 0.9 g | Tiny crappie jigs, micro finesse |
| 1/16 | 1.8 g | Small panfish/trout jigs |
| 1/8 | 3.5 g | Light shaky head, small spinners |
| 3/16 | 5.3 g | Ned rig, finesse drop-shot weight |
| 1/4 | 7.1 g | Small jigs, spinnerbaits, jerkbaits |
| 3/8 | 10.6 g | Bass jigs, spinnerbaits, chatterbaits |
| 1/2 | 14.2 g | All-around bass jig, larger crankbaits |
| 3/4 | 21.3 g | Heavier jigs, big spinnerbaits, swim jigs |
| 1 | 28.3 g | Heavy jigs, big swimbaits, deep cranks |
| 1 1/2 | 42.5 g | Punching weights, big swimbaits |
| 2 | 56.7 g | Heavy swimbaits, glide baits |
| 4 | 113.4 g | Big musky / large saltwater jigs |
Rod Length: Feet/Inches ↔ Centimeters/Meters
US tackle lists length as feet-and-inches (7'3"); Japanese and European brands list it in centimeters or meters (221 cm or 2.21 m). All three update together below.
Rod Power Chart (UL to XXH)
Power describes how much weight it takes to flex the rod blank. Lighter powers handle smaller lures and thinner line; heavier powers throw bigger baits and pull fish out of cover. The ranges below are typical — manufacturers vary, especially across regional standards.
| Code | Name | Lure weight | Line | Common use |
|---|---|---|---|---|
| UL | Ultra-Light | 1/64–1/16 oz | 2–6 lb | Trout, panfish, crappie, finesse for small bass |
| L | Light | 1/16–1/4 oz | 4–8 lb | Crappie, trout, light finesse for bass |
| ML | Medium-Light | 1/8–3/8 oz | 6–12 lb | Drop-shot, ned rig, shaky head, finesse bass |
| M | Medium | 1/4–5/8 oz | 8–14 lb | Jerkbaits, smaller crankbaits, all-around finesse |
| MH | Medium-Heavy | 3/8–1 oz | 10–20 lb | Texas rig, jigs, spinnerbaits, all-around bass |
| H | Heavy | 1/2–2 oz | 15–25 lb | Frog, flipping/pitching, big jigs, heavy cover |
| XH | Extra-Heavy | 1–4 oz | 20–40 lb | Swimbaits, punching, large fish, surf |
| XXH | Extra-Extra-Heavy | 3–8 oz | 30–80 lb | Heavy swimbaits, musky, inshore big game |
Rod Action Chart (XF to S)
Action describes where the rod bends under load — the higher up the blank, the "faster" the action. Fast actions give crisper hooksets and better sensitivity; slower actions load progressively for casting big lures or protecting light line and small treble hooks.
| Code | Name | Bends in | Best for |
|---|---|---|---|
| XF | Extra-Fast | Top ~10% | Fast hooksets, single-hook plastics, drop-shot, sensitivity |
| F | Fast | Top ~25% | Most all-around bass fishing, jigs, jerkbaits, casting accuracy |
| MF | Moderate-Fast | Top ~33% | Treble-hook baits, crankbaits, jerkbaits where some give helps |
| M | Moderate | Top ~50% | Crankbaits, treble hooks, livebait — load the fish gradually |
| MS | Moderate-Slow | Top ~66% | Light line, small treble hooks, fly-rod-like presentation |
| R | Regular | Top ~75% | Casting big lures with long deep loads, parabolic feel |
| S | Slow | Full | Light tackle, panfish, very small treble baits |
Fish Weight Estimator
Estimate weight from length using the standard L³ ÷ factor formula. Each species has a different factor based on body shape. Real weights vary by 20–30% with season, fat content, and individual condition.
Length-cubed estimate using a 1,600 factor for this species. "Skinny" and "Fat" bracket roughly ±1 standard deviation (±15%) — typical body-condition spread you'd see in a healthy population. Pre-spawn females and fall-fattened fish often exceed the Fat estimate. At 18.0" / 46cm.
| Weight | What it feels like |
|---|---|
| 0.5 lb | A stick of butter or a full deck of cards |
| 1 lb | A can of White Monster, loaf of bread, box of four sticks of butter |
| 2 lb | A pineapple or a 1-liter bottle of water |
| 3 lb | A half-gallon of milk or a large bag of oranges |
| 4 lb | A standard bag of sugar, a large laptop, or a full 64 oz growler of water |
| 5 lb | A standard house brick |
| 7.5 lb | A heavy watermelon, or just under one gallon of water |
| 8.3 lb | One gallon of water |
| 10 lb | A large sack of potatoes, a full gallon of paint, or a medium Thanksgiving turkey |
| Stack | Length | Weight (full) |
|---|---|---|
| Half a can | 2.5 in | 0.5 lb |
| 1 can | 4.8 in | 0.8 lb |
| 2 cans stacked | 9.5 in | 1.5 lb |
| 3 cans stacked | 14 in | 2.5 lb |
| 6-pack tall | 2.5 ft | 5 lb |
| 12 cans stacked | 4.8 ft | 10 lb |
A Guide to Rod Guides (Fuji)
Fuji dominates the high-end rod guide market — most rods over $80 ship with their components. Guide quality affects casting distance (smoothness of the inner ring), durability (hardness rating), and rod weight (frame mass). Here's the practical hierarchy.
Ring materials (the inner liner the line touches)
| Material | Hardness | Heat | Weight | Cost | Notes |
|---|---|---|---|---|---|
| SiC (Silicon Carbide) | Highest | Best | Light | Premium | Top-tier; standard on $200+ rods. Slick on line, dissipates heat from braid friction, extremely durable. |
| Torzite | Higher than SiC | Excellent | Lightest | Top | Fuji's flagship ring, found on the highest-end JDM and US rods. Thinner cross-section than SiC for less line slap. |
| Alconite | High | Very good | Light | Mid-high | Workhorse mid-tier on $100–200 rods. 90% of SiC performance at 60% of cost. Hard to beat in value. |
| Hardloy | Medium-high | Good | Med | Mid | Budget Fuji option, often on $60–120 rods. Fine for mono/fluoro; slightly more friction with braid. |
| Aluminum Oxide (alconite-O / O-ring) | Medium | Acceptable | Med-heavy | Budget | Sub-$80 rods. Performs OK with mono and fluoro; not ideal for high-speed braid (heat buildup, faster wear). |
Frame types (the metal cage around the ring)
| Series | Profile | Weight | Notes |
|---|---|---|---|
| K-Series (KW / KL / KT) | Tangle-free | Light | Industry standard since ~2010. Sloped frame angles braided line away from snags. KW is the casting workhorse. |
| T1 Concept / Stainless TZ | Standard sloped | Medium | Older but still common. T1 Concept = 1-piece stainless construction; slightly heavier than titanium but durable. |
| Titanium frame (Ti) | Anti-corrosion | Lightest | Top-tier rods. Saltwater-friendly, doesn't rust, doesn't take a set when bent. ~30% lighter than stainless but cost premium. |
| Concept-O / O-frames | Traditional ring frame | Heavier | Legacy frame on budget rods. Heavier and more prone to tangle with braid; mostly fine for spinning mono. |
Practical rule of thumb: For rods you'll use with braid, prioritize ring material (SiC or Alconite minimum). For rods you'll fish in saltwater, prioritize frame material (titanium > stainless). For everyday freshwater bass with fluorocarbon, Alconite K-Series guides on a stainless frame is the sweet spot.
