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.
Shrinkage allowance — finished size ↔ cut size
Calculate required pattern cut sizes from finished garment specs or expected post-wash sizes.
Steel grade equivalents — ASTM ↔ EN ↔ JIS standards
Cross-reference standard steel grades across ASTM/AISI, EN/DIN, and JIS systems. Includes chemical composition and key mechanical limits.
MAC address formats — colon ↔ hyphen ↔ Cisco notation
Convert physical MAC addresses between IEEE colon, hyphen, Cisco dot format, and raw hex strings.
Cable run — signal type + length → gauge required
Compute copper loop line resistance, voltage drop, and power loss to recommend the optimal wire gauge size (AWG).
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.
Wire feed speed ↔ amperage — MIG welding settings
Calculate MIG wire feed speed (WFS) and matching amperage. Includes gas recommendations and presets for steel, stainless, and aluminum.
