Calculate fishing line strength and leader size for target species, technique, and drag setting based on line type and test rating.
Estimate fish weight from length and girth measurements using species-specific formulas when you do not have a scale on the water.
Calculate optimal trolling speed in mph and knots for target fish species, lure type, and desired lure running depth on lakes or oceans.
Deep frame: ~8 lb (~0.67 gal) when fully capped. Medium: ~6 lb. Shallow: ~4 lb. Capacity assumes standard Langstroth dimensions and fully cured honey.
Honey (lb) = frames × fill% × frame capacity (lb)Honey weighs ~12 lb per gallon (1.42 kg/L), varying slightly with moisture content and floral source.
Volume (gal) = weight (lb) / 12Average US colony produces 30–60 lb surplus honey annually in good conditions. Strong colonies in major flows may fill a super (9 frames × 6 lb = 54 lb) in 2–3 weeks.
Annual yield = Σ harvest events × frames × capacity × fill%Updated: July 2026
9 × 0.90 × 6 lb = 48.6 lb honey ≈ 4.05 gallons. Yields roughly 40–45 lb after extraction loss and cappings.
Two medium supers, 9 frames each at 85%: 2 × 9 × 0.85 × 6 = 91.8 lb total. Bottling at 12 lb/gal ≈ 7.6 gallons — plan jars accordingly.
New colony first year: often 0–30 lb surplus as they build comb. Calculator with 5 medium frames at 70% = 21 lb — realistic first harvest if established by mid-summer.
Nectar above 18.6% moisture will ferment. Wait for capping or use a refractometer. Uncapped frames reduce average yield quality, not just weight.
Honey in brood boxes belongs to the colony for brood rearing and winter stores. Harvest from supers only — frames below the queen excluder are colony reserves.
Honey harvest planning requires estimating yield from capped frames before extraction. This calculator projects honey volume and weight from super frame count, frame size, and average fill percentage.
