NPK Fertilizer Blend Designer
Calculate exact commercial fertilizer weights (Nitrogen, Phosphate, Potash) required to hit crop nutrient targets.
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.
Atomic mass units ↔ grams — mole calculations
Convert Atomic Mass Units (u / Da) to grams or kilograms, and compute molar quantities of chemical elements.
Wood moisture content ↔ shrinkage percentage
Calculate expected wood dimensional shrinkage (radial, tangential, volumetric) based on changes in wood moisture content below fiber saturation point.
International Hat Size Matcher
Convert hat dimensions across US, UK, and European standards.
ROCK-CLIMBING Utilities
Choose a specialized option to begin instant real-time conversion.
Hold size ↔ finger force — crimp load estimation
Estimate skeletal finger force and crimp tendon pulley loads (A2/A4) based on edge/hold size (mm) and climber weight.
Rope elongation — fall factor ↔ impact force
Calculate fall factors, dynamic rope elongation, and peak impact force on the anchor system during climber falls.
Anchor load — number of bolts ↔ force distribution
Analyze force distribution, load multiplication, and tri-axial angle forces across multiple anchor bolts.
Grade converter — Yosemite ↔ French ↔ UIAA ↔ Australian
Convert climbing difficulty grades across Yosemite Decimal System (YDS), French, UIAA, Ewbank, and bouldering scales.
