Astrological Gem Analysis - Which is the right Jyotish Gem for you? The minimum prescribed weight is 400 mg for moderate quality Emerald ('Panna'). A lesser weight gem will also work equally well if it is of better quality. 'Ratti' is the unit to measure weight of gemstone in India. Traditional astrologers still recommend gemstones in 'Ratti' for wearing purpose. 'Standard Ratti' has the weight of 120 mg. as compared to 'Big Ratti' of 180 mg. Some scholars say that we must wear gemstone as per our body weight. However, I would also like to mention here that recommendation just on the basis of body weight is a myth and not described in any sacred text. One carat is equal to 1/5 of a gram (200 milligrams or 0.20 gram). Colour: Should be slightly bluish or yellowish green.

Clarity: Emeralds are the most heavily flawed Jyotish gemstone. Therefore, it is very, very difficult to find nearly eye flawless emeralds, but these are the best for Jyotish. The gem can be of any shape. Ratti carat conversion | Ratti to Carat Converter | Carat Ratti Calculator.

A month ago we received a strange request, “ I need a exactly 781 mg Emerald set in a ring that has equal parts of silver and lead, can you provide me with such a ring?” Thanks to Google Conversion tools we plugged in 781 mg and when it converts to carats we get a figure of 3.905 carats. This is what the Gemstoneuniverse team replied back: Thank you for your mail message. 781 mg translates to 3.905 carats. You can view the Gemstoneuniverse inventory online and choose an Emerald in this weight range. After a couple of days we received a reply from him stating that there is not a single Emerald that weighs 3.905 carats. To which the Gemstoneuniverse team replied: Thank you for your mail message, unfortunately at present time we do not have an exact 3.905 carats emerald.

Meanwhile no sacred text recommends this combination. What is a Ratti? India weight and measurement history. India uses metric system. Historically, British System, and Akbar system were used for nearly five previous centuries History I do not plan to cover ancient systems. Last four weights and Measure Systems of significance are as follows: 1. 2. 3. 4. During pre-Akbar period, weights and measure system varied from region to region, commodity to commodity, and rural to urban areas. British entered India as traders. In 1941, the Punjab Weight and Measures act provided a sense of uniformity. Current Conversion Standard In 1956, For metric conversion, Government of India defined the Seer as follows: One Seer = 0.93310 kilogram exact The UN (1966) set One Seer = 2.057 pounds on average. 1 Maund = 40 Seer = 100 Troy Pounds Exact 1 Seer = 80 Tola 1 Tola = 11.66375 gram Pre Akbar System I have included the weights and measures systems popular in North India. 1 Dhan (weight of one wheat berry) = 4 Grain of Rice 1Ratti = 4 Dhan Ratti is seed of a plant 'Abrus precatorius'. 1 Masha = 8 Ratti Conversion 1. 2. 3.

Theoretical Nominal Weight - Page 12. Steel Buyer Basics – Theoretical Nominal Weight Theoretical Nominal Weight (TNW) has been around the longest and is probably the least understood by many of today’s buyers and sellers. TNW is also called “nominal”, “book weight”, “actual book weight”, “SMACNA weight”. For steel buyers, one of the key basics is the understanding there are different ways to buy steel. Steel buyers that are aware of the different methods and recognize the terminology and weight calculations will lessen the risks of their company ever being taken advantage of by another company. All steel is not created equal. Weight is weight only when it is actually weighed. Otherwise, theoretical calculations come into play which will adjust the weight based on footage and the nominal/actual density factor of the steel (see previous editions of STEEL MARKET UPDATE for more explanations). I can tell you the Nominal weight of any galvanized coil in your inventory if you give me the gauge, width and linear footage.

History Of Information Technology — Introduction to Information and Communication Technology. Introduction Information technology has been around for a long, long time. Basically as long as people have been around, information technology has been around because there were always ways of communicating through technology available at that point in time. There are 4 main ages that divide up the history of information technology. Only the latest age (electronic) and some of the electromechanical age really affects us today, but it is important to learn about how we got to the point we are at with technology today.

Ages Premechanical The premechanical age is the earliest age of information technology. Petroglyph As alphabets became more popluar and more people were writing information down, pens and paper began to be developed. Now that people were writing a lot of information down they needed ways to keep it all in permanent storage. Also during this period were the first numbering systems.
