The Monarch Butterfly has a very low 0.168 kg/m 2 wing loading The McDonnell Douglas MD-11 has a high 837 kg/m 2 maximum wing loading. In aerodynamics, wing loading is the total weight of an aircraft or flying animal divided by the area of its wing.
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 ...
One slug is a mass equal to 32.17405 lb (14.59390 kg) based on standard gravity, the international foot, and the avoirdupois pound. [3] In other words, at the Earth's surface (in standard gravity), an object with a mass of 1 slug weighs approximately 32.17405 lbf or 143.1173 N. [ 4 ] [ 5 ]
At IUPAC standard temperature and pressure (0 °C and 100 kPa), dry air has a density of approximately 1.2754 kg/m 3. At 20 °C and 101.325 kPa, dry air has a density of 1.2041 kg/m 3. At 70 °F and 14.696 psi, dry air has a density of 0.074887 lb/ft 3.

The 35.1 pounds is the 'theoretical" weight of the package if it had a density of 166 in 3 /lb or 10.4 lb/ft 3: (18 × 18 × 18) = 3.375 ft 3 × 10.4 lb/ft 3 = 35.1 lb. Note that for the USPS there are two different calculations for DIM weight: (L × W × H)/194 for domestic shipments and (L × W × H)/166 for international shipments.
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.
For example, a 152.4 cm (5 ft 0 in) tall person at an ideal body weight of 48 kg (106 lb) gives a normal BMI of 20.74 and CI of 13.6, while a 200 cm (6 ft 7 in) tall person with a weight of 100 kg (220 lb) gives a BMI of 24.84, very close to an overweight BMI of 25, and a CI of 12.4, very close to a normal CI of 12.
