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.
Calculate volume in cubic feet from thickness, width, and length. For metric inputs, convert to cubic meters and apply density in kg/m³.
Volume (bd ft) = (T × W × L) / 144Each species has a published oven-dry density (typically at 12% MC). Green lumber weighs more due to free water above fiber saturation; kiln-dried stock uses standard published values.
Weight = Volume × Density × MC_factorAbove 30% MC, free water adds significant weight. Below fiber saturation, density increases roughly linearly with MC. Most calculators use density values at 12% MC as baseline.

Fifty kiln-dried SPF 2×4×8 studs at 12% MC weigh roughly 2,400 lbs total. Useful for checking if a half-ton truck with 1,500 lb payload capacity needs multiple trips.
A 3/4×10×36 inch white oak shelf at 12% MC weighs about 12 lbs. Combined with books and objects, total load on brackets must stay under their rated capacity.
An 8×8×12 foot green white oak beam at 40% MC can weigh over 800 lbs. Critical for crane sizing and crew safety during raising.
Always use actual measured thickness and width. A "2×10" is 1.5×9.25 inches — using 2×10 nominal dimensions overestimates weight by about 35%.
Green lumber can weigh 40–80% more than kiln-dried. Specify moisture content or select "green" density values for felled logs and freshly milled stock.
Knowing lumber weight helps plan truck loads, shelf capacity, and shipping costs. This calculator combines board dimensions, species-specific density, and moisture content to estimate total weight for individual boards or full bundles.
