The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. The equivalent weight of an element is the mass of a mole of the element divided by the element's usual valence. That is, in grams, the atomic weight of the element divided by the usual ...
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 .
An equivalent definition of the dyne is "that force which, acting for one second, will produce a change of velocity of one centimetre per second in a mass of one gram". [ 3 ] One dyne is equal to 10 micronewtons, 10 −5 N or to 10 nsn (nano sthenes ) in the old metre–tonne–second system of units .
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]).
1 Kancha = 5 Siki. 1 Chhataank = 4 Kancha. 1 Chhataank = 5 Bhari. 1 Adh-pav = 2 Chhatank = 1/8 Seer. 1 Pav = 2 Adh-pav = ¼ Seer (Pav means ¼) The unit pav is still used to this date however, it has been modified to "a fourth of a kilogram". 1 Adher = 2 Pav = ½ Seer. In Hindi ½ Seer = Adha (½) Seer, or Adher.
Dram (unit) The dram (alternative British spelling drachm; apothecary symbol ʒ or ℨ; [ a] abbreviated dr) [ 4][ 5]: C-6–C-7 [ 6] is a unit of mass in the avoirdupois system, and both a unit of mass and a unit of volume in the apothecaries' system. [ 5] It was originally both a coin and a weight in ancient Greece. [ 7]
The dalton or unified atomic mass unit (symbols: Da or u) is a non-SI unit of mass defined as 1 12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. [ 1][ 2] The atomic mass constant, denoted mu, is defined identically, giving mu = 1 12 m(12C) = 1 Da. [ 3]
The tola ( Hindi: तोला / Urdu: تولا, romanized : tolā; also transliterated as tolah or tole) is a traditional Ancient Indian and South Asian unit of mass, now standardised as 180 grains ( 11.6638038 grams) or exactly 3⁄8 troy ounce. It was the base unit of mass in the British Indian system of weights and measures introduced in ...
