  2. Federal Bridge Gross Weight Formula - Wikipedia

    In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below). For example, a 25-foot (7.6 m) three-axle dump truck would have a gross weight limit of 54,500 pounds (24,700 kg), instead of 80,000 pounds (36,000 kg), which is the standard weight limit for 63-foot (19.2 m) five-axle tractor-trailer.

  3. Floor area ratio - Wikipedia

    en.wikipedia.org/wiki/Floor_area_ratio

    In India FAR and FSI are both used. FAR regulations vary from city to city and generally it is from 1.3 to 3.25. In Mumbai 1.33 is the norm but higher FSI is allowed along the Metro rail line and slum areas like Dharavi. In Bangalore, 40 feet streets allow only an FAR of 1.75 but 100 feet streets allow 3.25 FAR. [citation needed]

  4. Poundal - Wikipedia

    en.wikipedia.org/wiki/Poundal

    Since a pound of force (pound force) accelerates a pound of mass at 32.174 049 ft/s 2 (9.80665 m/s 2; the acceleration of gravity, g), we can scale down the unit of force to compensate, giving us one that accelerates 1 pound mass at 1 ft/s 2 rather than at 32.174 049 ft/s 2; and that is the poundal, which is approximately 1 ⁄ 32 pound force.

  5. Conversion of units - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_units

    Because of the identity property of multiplication, multiplying any quantity (physical or not) by the dimensionless 1 does not change that quantity. [5] Once this and the conversion factor for seconds per hour have been multiplied by the original fraction to cancel out the units mile and hour, 10 miles per hour converts to 4.4704 metres per second.

  6. Board foot - Wikipedia

    en.wikipedia.org/wiki/Board_foot

    The board foot or board-foot is a unit of measurement for the volume of lumber in the United States and Canada. [1] It equals the volume of a board that is one foot (30.5 cm) in length, one foot in width, and one inch (2.54 cm) in thickness, or exactly 2.359 737 216 liters .

  7. Pound (force) - Wikipedia

    en.wikipedia.org/wiki/Pound_(force)

    The pound-force is the product of one avoirdupois pound (exactly 0.45359237 kg) and the standard acceleration due to gravity, approximately 32.174049 ft/s 2 (9.80665 m/s 2).

  8. Specific weight - Wikipedia

    en.wikipedia.org/wiki/Specific_weight

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

  9. Acre-foot - Wikipedia

    en.wikipedia.org/wiki/Acre-foot

    Since an acre is defined as a chain by a furlong (i.e. 66 ft × 660 ft or 20.12 m × 201.17 m), an acre-foot is 43,560 cubic feet (1,233.5 m 3). There has been two definitions of the acre-foot (differing by about 0.0006%), using either the international foot (0.3048 m) or a U.S. survey foot (exactly ⁠ 1200 / 3937 ⁠ meters since
