  2. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres (⁠ 1 100 ⁠ m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.

  3. Shoe size - Wikipedia

    The last is typically longer than the foot heel to toe length by 4 ⁄ 3 cm (13.33 mm) to 53 cm (16.67 mm), or 2 to 2 + 1 ⁄ 2 Paris points, so to determine the shoe size based on actual foot length one must add 2 Paris points. Because a Paris point is 2 ⁄ 3 of a centimetre, a centimetre is 3 ⁄ 2 Paris points, and the formula is as ...

  4. Millimetre - Wikipedia

    en.wikipedia.org/wiki/Millimetre

    The microwave is between 1 meter to 1 millimeter. The millimetre (international spelling; SI unit symbol mm) or millimeter (American spelling) is a unit of length in the International System of Units (SI), equal to one thousandth of a metre, which is the SI base unit of length. Therefore, there are one thousand millimetres in a metre.

  5. 3.7 cm Pak 36 - Wikipedia

    en.wikipedia.org/wiki/3.7_cm_Pak_36

    Design of a horse-drawn, 3.7 cm anti-tank gun (designated 3.7 cm Pak L/45) by Rheinmetall commenced in 1924 and the first guns were issued in 1928. [5] By the early 1930s, it was apparent that horse-drawn artillery was obsolescent, and the gun was modified for motorized transport by substituting magnesium-alloy wheels and pneumatic tires for the original spoked wooden wheels, allowing it to be ...

  6. Orders of magnitude (molar concentration) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(molar...

    Orders of magnitude (molar concentration) This page lists examples of the orders of magnitude of molar concentration. Source values are parenthesized where unit conversions were performed. M denotes the non-SI unit molar: 1 M = 1 mol/L = 10 −3 mol/m 3.

  7. Centimetre - Wikipedia

    en.wikipedia.org/wiki/Centimetre

    A centimetre or centimeter (US/Philippine spelling), with SI symbol cm, is a unit of length in the International System of Units (SI) equal to one hundredth of a metre, centi being the SI prefix for a factor of ⁠ 1 100 ⁠. [1] Equivalently, there are 100 centimetres in 1 metre. The centimetre was the base unit of length in the now deprecated ...

  8. Centimetre or millimetre of water - Wikipedia

    en.wikipedia.org/wiki/Centimetre_or_millimetre...

    A centimetre of water[1] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH2O (4°C) = 999.9720 kg/m3 × 9.80665 m/s2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum ...
