Choose a specialized option to begin instant real-time conversion.
Displacement tonnage ↔ cubic meters — ship buoyancy
Convert ship displacement tonnage to submerged volume (m³) and buoyancy force. Choose between freshwater and saltwater standards.
Propeller pitch ↔ boat speed — theoretical boat speed
Calculate theoretical boat speed and actual speed based on propeller pitch, engine RPM, gear ratio, and hull slip percentages.
Engine power ↔ hull speed — planing vs displacement
Estimate maximum displacement hull speeds (LWL formula) or calculate planing hull speeds using Crouch's classic marine formula.
Fuel burn rate — engine HP ↔ liters per hour
Calculate marine engine fuel consumption (liters/hr or gal/hr) using Brake Specific Fuel Consumption (BSFC) or standard marine power constants.
Rope breaking strength — diameter ↔ material ↔ load rating
Estimate minimum breaking strength (MBS) and safe working load (SWL) based on line diameter, material (Dyneema, Nylon, etc.), and safety factors.
