NATURAL SYSTEM OF UNITS IN GENERAL RELATIVITY ALAN L. MYERS Abstract. The gravitational metric system is a non-standard system of units, which does not comply with the International System of Units. All other units are defined based on these seven, and they are really nothing more than convenient shorthands in notation. In this system, the general form of Newton's second law of mechanics remains unchanged, but it contains a proportionality constant k. All other mechanical quantities, and specifically mass, are expressed in terms of combinations of these three units. It is built on the three base quantities length, time and force with base units metre, second and kilopond respectively. This is how it differs from absolute system;because g is not absolute,it is variable. Last revised: 20 July 2004. For your calculation, you must convert all your units into kg, m, s, so everything is consistent. Any measurements in mechanics can be expressed in such a system. Gravitational potential energy (GPE) is an important physical concept that describes the energy something possesses due to its position in a gravitational field. Online conversion from Tonne-force (Gravitational Metric System) to Atomic Unit Of Force (Atomic Physics Units). A system of units is said to be gravitational if its units for length, time, and force are base units, that is, not defined in terms of other units.

A gravitational constant has a value of 6.673 84 x 10^-11 m^3 kg^-1 s^-2 in English units, which can also be written as G = 6.673 x 10^-11 N m^2 kg^-2. Gravitational systems contrast with absolute systems. In the British gravitational system, the three base units are the foot, the second, and the pound-force. Customary Units. British gravitational system: A non-SI (International System) system of measurement in which the foot, pound-force and second are the base units of length, force and time, respectively. The system is called “gravitational” because the unit of force is often defined by the effect of gravity on a physical prototype. This is how it differs from absolute system;because g is not absolute,it is variable. The unit of mass, the slug, was then derived from the pound-force by defining it as that mass that will accelerate at 1 foot per second per second when a 1 pound-force acts upon it. Introduction ; There is a difference between dimensions and units. (Redirected from British Gravitational System) The foot–pound–second system or FPS system is a system of units built on three fundamental units: the foot for length, the (avoirdupois) pound for either mass or force (see below), and the second for time. The force would be a Newton as all forces can be expressed. The unit ‘kgf’ or ‘kilogram force’ is a gravitational unit of force. Appendix table 8 Comparison table between SI and CGS/system of gravitational units Representative quantity SI units Absolute system of units Gravity unit system m - kg ft - lb m - kgf ft - lbf G is not a force, it is called the universal gravitational constant. Define gravitational constant. The system is called “gravitational” because the unit of force is often defined by the effect of gravity on a physical prototype. 1 kgf = 9.8 N. where G is the gravitational constant, and F is the gravitational force. The GPE formula GPE = mgh shows that it depends on the mass of the object, the acceleration due to gravity and the height of the object. What is the SI unit of G and g?
