    {{convert|123|cuyd|m3+board feet}} → 123 cubic yards (94 m 3; 40,000 board feet) The following converts a pressure to four output units. The precision is 1 (1 decimal place), and units are abbreviated and linked.

  4. Shoe size - Wikipedia

    en.wikipedia.org/wiki/Shoe_size

    The perimeter of the foot is the length of the foot circumference, measured with a flexible tape at the same points as foot width. The origin of the grade is zero. The labeling typically includes foot length, followed by an optional foot width: a shoe size of 280/110 indicates a foot length of 280 millimetres (11.0 in) and width of 110 ...

    The hyl is a unit of mass equal to 1 kgf⋅m −1 ⋅s 2 (9.806 65 kg). The poncelet (p) is a unit of power equal to 1 kgf ⋅m⋅s −1 ( 980.665 W ). The technical atmosphere (at) is a (non-coherent) unit of pressure equal to 1 kgf ⋅cm −2 ( 98 066 .5 Pa ).

  8. Kilogram - Wikipedia

    en.wikipedia.org/wiki/Kilogram

    The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10 −34 when expressed in the unit J⋅s, which is equal to kg⋅m 2 ⋅s −1, where the metre and the second are defined in terms of c and Δν Cs. —

    en.wikipedia.org/wiki/Metric_system

    An SI derived unit is a named combination of base units such as hertz (cycles per second), newton (kg⋅m/s 2), and tesla (1 kg⋅s −2 ⋅A −1) and in the case of Celsius a shifted scale from Kelvin. Certain units have been officially accepted for use with the SI.
