Stocking density — fish size ↔ liters per kg
Calculate stocking density (kg/m³ or L/kg), total biomass, and maximum safe fish count based on tank volume and average fish weight.
Atomic mass units ↔ grams — mole calculations
Convert Atomic Mass Units (u / Da) to grams or kilograms, and compute molar quantities of chemical elements.
Water Depth & Pressure Converter
Convert ocean depth between fathoms, meters, and feet, and estimate hydrostatic pressure and bathymetric marine zones.
Ore dilution — grade ↔ waste ↔ recovered grade
Calculate recovered ore grade, tonnage adjustments, dilution percentages, and mining waste contamination levels.
Thread count ↔ fabric quality rating
Calculate and convert cotton single-ply thread counts to analyze and rate fabric quality and softness.
GLIDING-SOARING Utilities
Choose a specialized option to begin instant real-time conversion.
Glide ratio (L/D) — distance ↔ height lost
Convert lift-to-drag glide ratio into horizontal distance reached versus vertical altitude loss under zero-wind and head/tailwind conditions.
Sink rate — airspeed ↔ altitude loss per minute
Calculate glider sink rate in knots or m/s from airspeed and polar parameters, yielding altitude loss rate.
Thermal strength — climb rate ↔ core diameter estimate
Estimate thermal core diameter, updraft velocity distribution (Gaussian profile), and optimal bank angle for maximum climb rate.
Speed to fly — polar curve ↔ McCready interthermal speed
Calculate the optimum speed to fly between thermals based on the glider polar curve, expected next thermal climb rate, and headwind/sink.
Final glide calculator — height + glide ratio → reach distance
Analyze safety margins, required arrival altitude, wind impact, and distance reachable for your glider final glide phase.
