About Micrometres per Second
A micrometre per second (µm/s) is 10⁻⁶ m/s - the speed of cell motility, bacteria, and precision machining feeds. E. coli swims at 20-30 µm/s; the fastest bacteria (Thiovulum majus) reach 600 µm/s. Neutrophils chasing a chemoattractant move at 10-20 µm/s. Microfluidic lab-on-chip analytical channels flow at 1-1,000 µm/s. Diamond-turning lathe in-feeds for optical surfaces are 1-100 µm/s. Fast glacier centrelines move ~1-10 µm/s (~100 m/year). 1 µm/s = 10⁻⁶ 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.
