  2. FFF system - Wikipedia

    en.wikipedia.org/wiki/FFF_system

    One furlong per fortnight is a speed that would be barely noticeable to the naked eye. It converts to: 1.663 × 10 −4 m/s, (i.e. 0.1663 mm/s), roughly 1 cm/min (to within 1 part in 400), [b] 5.987 × 10 −4 km/h, roughly 3 ⁄ 8 in/min, 3.720 × 10 −4 mph, the speed of the tip of a 3 + 3 ⁄ 4 inch minute hand.

  3. Visibility - Wikipedia

    en.wikipedia.org/wiki/Visibility

    The international definition of fog is a visibility of less than 1 km (3,300 ft); mist is a visibility of between 1 km (0.62 mi) and 2 km (1.2 mi) and haze from 2 km (1.2 mi) to 5 km (3.1 mi). Fog and mist are generally assumed to be composed principally of water droplets, haze and smoke can be of smaller particle size.

    kilometre (km) or kilometer is a metric unit used, outside the US, to measure the length of a journey; the international statute mile (mi) is used in the US; 1 mi = 1.609344 km; nautical mile is rarely used to derive units of transportation quantity.

    Starting in 2005 (under the GP2 Series name), Formula 2 cars were powered by 4.0 litres (244 cubic inches) V8, four-stroke piston, Otto cycle unleaded gasoline-burning, prototype production-based, naturally-aspirated engines, produced by Mecachrome. Per Formula 2 rules, the engines sold for no more than €70,000 and were rev-limited to 10,000 rpm.

  7. Conversion of units - Wikipedia

    NO x molar mass = 46 kg/kmol = 46 g/mol Flow rate of flue gas = 20 cubic metres per minute = 20 m 3 /min The flue gas exits the furnace at 0 °C temperature and 101.325 kPa absolute pressure. The molar volume of a gas at 0 °C temperature and 101.325 kPa is 22.414 m 3 /kmol.

  8. Speed of light - Wikipedia

    en.wikipedia.org/wiki/Speed_of_Light

    For example, for visible light, the refractive index of glass is typically around 1.5, meaning that light in glass travels at ⁠ c / 1.5 ⁠ ≈ 200 000 km/s (124 000 mi/s); the refractive index of air for visible light is about 1.0003, so the speed of light in air is about 90 km/s (56 mi/s) slower than c.
