The standard acceleration of gravity or standard acceleration of free fall, often called simply standard gravity and denoted by ɡ 0 or ɡ n, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth.
This translates to a hoppus foot being equal to 1.273 cubic feet (2,200 in 3; 0.0360 m 3). The hoppus board foot, when milled, yields about one board foot . The volume yielded by the quarter-girth formula is 78.54% of cubic measure (i.e. 1 ft 3 = 0.7854 h ft; 1 h ft = 1.273 ft 3 ).
Medieval blast furnaces were about 10 feet (3.0 m) tall and made of fireproof brick; forced air was usually provided by hand-operated bellows. [108] Modern blast furnaces have grown much bigger, with hearths fourteen meters in diameter that allow them to produce thousands of tons of iron each day, but essentially operate in much the same way as ...
These problems tend to be very small, but may add up to a few meters (tens of feet) of inaccuracy. [7] For very precise positioning (e.g., in geodesy), these effects can be eliminated by differential GPS: the simultaneous use of two or more receivers at several survey points.
A short-necked recyclable beer-bottle with a rounded body; the word is a nickname for a person who is short and fat. It used to be 12 Imperial ounces [341 ml] (3/5 of an Imperial pint), like the Canadian "stumpy" beer bottles. It was rounded down to 340 ml when South Africa converted to the metric system in 1970.
But, in concept, there is no problem adding quantities of the same dimension expressed in different units. For example, 1 metre added to 1 foot is a length, but one cannot derive that length by simply adding 1 and 1. A conversion factor, which is a ratio of like-dimensioned quantities and is equal to the dimensionless unity, is needed:
The geodetic and geocentric latitudes are equal at the equator and at the poles but at other latitudes they differ by a few minutes of arc. Taking the value of the squared eccentricity as 0.0067 (it depends on the choice of ellipsoid) the maximum difference of ϕ − θ {\displaystyle \phi {-}\theta } may be shown to be about 11.5 minutes of ...
