See Weight for detail of mass/weight distinction and conversion. Avoirdupois is a system of mass based on a pound of 16 ounces, while Troy weight is the system of mass where 12 troy ounces equals one troy pound. The symbol g 0 is used to denote standard gravity in order to avoid confusion with the (upright) g symbol for gram.
This means that at this layer L = 0 and T = 220 K, so that the exponential drop is faster, with H TP = 6.3 km for air (6.5 for nitrogen, 5.7 for oxygen and 4.2 for carbon dioxide). Both the pressure and density obey this law, so, denoting the height of the border between the troposphere and the tropopause as U :

kilometre (km) or kilometer is a metric unit used, outside the US, to measure the length of a journey; the international statute mile (mi) is used in the US; 1 mi = 1.609344 km; nautical mile is rarely used to derive units of transportation quantity.
Determination of the rod, using the length of the left foot of 16 randomly chosen people coming from church service. Surveyors in the United States continue to use: chain (22 yards, or 20.1168 m) rod (also called pole or perch) (quarter of a chain, 5 1 ⁄ 2 yards, or 5.0292 m)
An adult human foot is about 28 cm (11 in) long. The decimetre ( SI symbol: dm ) is a unit of length in the metric system equal to 10 −1 metres ( 1 / 10 m = 0.1 m ). To help compare different orders of magnitude , this section lists lengths between 10 centimeters and 100 centimeters (10 −1 meter and 1 meter).
A number of different units of measurement were used in Sri Lanka to measure quantities like length, mass and capacity from very ancient times. [1] Under the British Empire, imperial units became the official units of measurement [2] and remained so until Sri Lanka adopted the metric system in the 1970s.
