The tonne (t) is an SI-compatible unit of mass equal to a megagram ( Mg ), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes. For example, a gigagram ( Gg) or 10 9 g is 10 3 tonnes, commonly called a kilotonne .

On the previous IPTS-68 scale the densities [6] at 20 °C and 4 °C are, respectively, 0.9982041 and 0.9999720 resulting in an RD (20 °C/4 °C) value for water of 0.99823205. The temperatures of the two materials may be explicitly stated in the density symbols; for example: relative density: 8.15 20 °C 4 °C; or specific gravity: 2.432 15 0
v. t. e. In quantum mechanics, the measurement problem is the problem of definite outcomes: quantum systems have superpositions but quantum measurements only give one definite result. [ 1][ 2] The wave function in quantum mechanics evolves deterministically according to the Schrödinger equation as a linear superposition of different states.
From these figures for the size of a Biblical ell, that of the basic unit — the finger-breadth ( Etzba) — can be calculated to be either 2.1 or 2.2 cm (0.83 or 0.87 in); Rav Avraham Chaim Naeh approximates at 2 cm (0.79 in); Talmudic scholar Chazon Ish at 2.38 cm (0.94 in). The mile ( Mil) is thus about 963 or 1146 meters (3160 or 3760 ft ...
The general relationship between absorbed dose and equivalent dose can be represented as. H = Q ⋅ D. where H is the equivalent dose, D is the absorbed dose, and Q is a dimensionless quality factor. Thus, for any quantity of D measured in Gy, the numerical value for H measured in Sv may be different.
The metre–tonne–second ( MTS) system of units was invented in France (hence the derived unit names sthène and pièze) where it became the legal system between 1919 and 1961. [1] It was adopted by the Soviet Union in 1933 and abolished there in 1955. It was a coherent metric system of units, much as SI and the centimetre–gram–second ...
It was originally defined as "the quantity or mass of radium emanation in equilibrium with one gram of radium (element)", [1] but is currently defined as 1 Ci = 3.7 × 10 10 decays per second [4] after more accurate measurements of the activity of 226 Ra (which has a specific activity of 3.66 × 10 10 Bq/g [5]).
