The result reported by Charles Hutton (1778) suggested a density of 4.5 g/cm 3 (4 + 1 / 2 times the density of water), about 20% below the modern value. [16] This immediately led to estimates on the densities and masses of the Sun , Moon and planets , sent by Hutton to Jérôme Lalande for inclusion in his planetary tables.
In unit systems where force is a derived unit, like in SI units, g c is equal to 1. In unit systems where force is a primary unit, like in imperial and US customary measurement systems, g c may or may not equal 1 depending on the units used, and value other than 1 may be required to obtain correct results.

CF (conductivity factor) is basically EC multiplied by 10, and is used in some places because it eliminates the need for a decimal point, so an EC of 0.1 is equal to a CF of 1. [ 1 ] Electrical conductivity can be expressed using a number of different units but the international standard is EC, and the unit of measurement is usually ...
The g-force acting on an object under acceleration can be much greater than 1 g, for example, the dragster pictured at top right can exert a horizontal g-force of 5.3 when accelerating. The g-force acting on an object under acceleration may be downwards, for example when cresting a sharp hill on a roller coaster.
[3] [4] [5] They deal with patent claims directed to such second or subsequent medical use, and, as explained in reason 22 of decision G 5/83, the Enlarged Board held that patent claims directed to such substances or compositions were allowable under the European Patent Convention (EPC) when worded as purpose-limited product claims, which are ...
That is, observed temperatures above 60 °F (or the base temperature used) typically correlate with a correction factor below "1", while temperatures below 60 °F correlate with a factor above "1". This concept lies in the basis for the kinetic theory of matter and thermal expansion of matter , which states as the temperature of a substance ...
Characteristic velocity or , or C-star is a measure of the combustion performance of a rocket engine independent of nozzle performance, and is used to compare different propellants and propulsion systems. c* should not be confused with c, which is the effective exhaust velocity related to the specific impulse by: =. Specific impulse and ...
The residue Res(f, c) of f at c is the coefficient a −1 of (z − c) −1 in the Laurent series expansion of f around c. Various methods exist for calculating this value, and the choice of which method to use depends on the function in question, and on the nature of the singularity.
