  2. Load factor (aeronautics) - Wikipedia

    en.wikipedia.org/wiki/Load_factor_(aeronautics)

    Since the load factor is the ratio of two forces, it is dimensionless. However, its units are traditionally referred to as g, because of the relation between load factor and apparent acceleration of gravity felt on board the aircraft. A load factor of one, or 1 g, represents conditions in straight and level flight, where the lift is equal to ...

  3. List of common display resolutions - Wikipedia

    en.wikipedia.org/wiki/List_of_common_display...

    This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio). This article lists computer monitor, television, digital film, and other graphics display resolutions that are in common use. Most of them use certain preferred numbers.

    This implies that all postcards have an aspect ratio in the range from 20∶17 = 1.18 to 12∶7 = 1.71, but the machinable aspect ratio is further restricted to a minimum of 1.30. The only ISO 216 size in the US postcard range is A6. The theoretical maximum aspect ratio for enveloped letters is 23∶7 = 3.29, but is explicitly limited to 2.50.

    The ratio of these diameters is 1:92, and there are 40 gauge sizes from 36 to 0000, or 39 steps. Because each successive gauge number increases cross sectional area by a constant multiple, diameters vary geometrically. Any two successive gauges (e.g., A and B) have diameters whose ratio (dia. B ÷ dia.

    36530115 TTT and 36381293 AAA (ratio % = 1.00409). 2087242 TCG and 2085226 CGA (ratio % = 1.00096), etc... In 2020, it is suggested that the physical properties of the dsDNA (double stranded DNA) and the tendency to maximum entropy of all the physical systems are the cause of Chargaff's second parity rule.

  7. Liquid-to-gas ratio - Wikipedia

    en.wikipedia.org/wiki/Liquid-to-gas_ratio

    This is commonly called the liquid-to-gas ratio (L/G ratio) and uses the units of gallons per 1,000 actual cubic feet or litres per cubic metre (L/m 3). Expressing the amount of liquid used as a ratio enables systems of different sizes to be readily compared.

    en.wikipedia.org/wiki/Snellen_chart

    A Snellen chart is an eye chart that can be used to measure visual acuity. Snellen charts are named after the Dutch ophthalmologist Herman Snellen who developed the chart in 1862 as a measurement tool for the acuity formula developed by his professor Franciscus Cornelius Donders .
