About Feet per Minute
A foot per minute (ft/min) = 5.08 × 10⁻³ m/s - the US standard for elevator speed, HVAC duct velocity, and conveyor speed. Residential lifts: 100-200 ft/min; commercial 200-400 ft/min; skyscraper express lifts 1,000-3,000 ft/min (Burj Khalifa 2,953 ft/min). HVAC low-velocity ductwork: 500-1,000 ft/min; medium-velocity 1,000-2,200 ft/min. Paper machine Fourdrinier wires: 200-6,000 ft/min. 1 ft/min = 0.00508 m/s.
About Furlong per Fortnight
A furlong per fortnight (fur/fn) is a deliberately archaic unit equal to exactly 201.168 ÷ 1,209,600 m/s ≈ 1.663 × 10⁻⁴ m/s - just slightly faster than a garden snail at full creep. One furlong (one-eighth of a mile = 201.168 m) and one fortnight (14 days = 1,209,600 s) are both perfectly legitimate historical measures, but their combination is cherished in physics teaching as a cautionary example of needlessly exotic unit choices. Expressing kinetic energy in kg·fur²/fn² or force in kg·fur/fn² illustrates instantly why the SI was universally adopted. The unit appears in satirical physics papers, recreational mathematics columns, and Terry Pratchett's Discworld novels as the native velocity unit of magical phenomena. The speed of light expressed in furlongs per fortnight is approximately 1.803 × 10¹² fur/fn. Snails travel at roughly 0.5-1 fur/fn; strong tidal rip currents reach 100-200 fur/fn. 1 fur/fn ≈ 1.663 × 10⁻⁴ m/s ≈ 0.599 km/h ≈ 0.372 mph.
