  2. Body mass index - Wikipedia

    en.wikipedia.org/wiki/Body_mass_index

    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.

  3. Power-to-weight ratio - Wikipedia

    en.wikipedia.org/wiki/Power-to-weight_ratio

    A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.

  4. Lifting gas - Wikipedia

    en.wikipedia.org/wiki/Lifting_gas

    1 m 3 × 1.202 kg/m 3 × 9.8 N/kg= 11.8 N. The amount of mass that can be lifted by helium in air at sea level is: (1.292 - 0.178) kg/m 3 = 1.114 kg/m 3. and the buoyant force for one m 3 of helium in air at sea level is: 1 m 3 × 1.114 kg/m 3 × 9.8 N/kg= 10.9 N. Thus hydrogen's additional buoyancy compared to helium is:

  5. Orders of magnitude (mass) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(mass)

    An overview of ranges of mass. To help compare different orders of magnitude, the following lists describe various mass levels between 10 −67 kg and 10 52 kg. The least massive thing listed here is a graviton, and the most massive thing is the observable universe.

  6. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    In light-water reactors, 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 kg of coal. [16] Comparatively, coal, gas, and petroleum are the current primary energy sources in the U.S. [17] but have a much lower energy ...

  7. Density - Wikipedia

    en.wikipedia.org/wiki/Density

    Densities using the following metric units all have exactly the same numerical value, one thousandth of the value in (kg/m 3). Liquid water has a density of about 1 kg/dm 3, making any of these SI units numerically convenient to use as most solids and liquids have densities between 0.1 and 20 kg/dm 3. kilogram per cubic decimetre (kg/dm 3)

  8. Schofield equation - Wikipedia

    en.wikipedia.org/wiki/Schofield_equation

    The Schofield Equation is a method of estimating the basal metabolic rate (BMR) of adult men and women published in 1985. [1]This is the equation used by the WHO in their technical report series. [2]

    The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
