WEIGHT:
The unit of weight is based on parm u. It is given as tranfal, which is 2.04*(10) v ra where v ra is approx one tol or 11.6 grams Weight is also represented through similes (pr m a) e.g., one fistful, etc.
In modern science, Einstein and other scientist have calculated weight by using the concept of interchangeability of matter into energy. They state that 1 kilogram of matter if transmuted completely in energy can generate 9 * (10) joules of energy which is enough to provide electricity to a small town for months together. Another way to define it is, as the quantity of heat required to convert 1000 tons of water into steam will weigh only 1/30 grams". Estimated weight of electron is 1.2(10.28)*10 grams and proton approximately 1837 times heavier than electron.
SPACE:
The unit of space is called prade a or space-point. It is defined as the space occupied by one parm u of matter under normal conditions. This prade a is even capable of accommodating infinite number of such particles and living beings under abnormal conditions. Every substance is described in terms of number of prade a or space points it occupies to describe its size. In computer terminology we may refer prade a as similar to pixels.
The units of measurement generally used for length, breadth, volume, etc are as follows:
Angula P da
H tha
finger breadth (from tip of the nail to the bottom of the finger 6 finger breadths (half span from tip of the thumb to the tip of little finger), p da is approx 4.5 inches Cubit (length of forearm from tip of middle finger to the elbow and approx 17 to 24 inches) Bow (or dand) approx 6 feet or 4 Cubit 4*2000 dhanu or 48000 feet or 9.03 miles or 14.4 kilometers approximately Rope varying values given. One such value is 1.15*10 21 miles or 1.84 * 10 kilometers

For area these units are squared and for volume these units are raised to the power three
Scientists talk of light years based on the speed of light at 332000 kilometers per second to measure distance between stars in the cosmic space. Thus the distance between two stars is indicated in terms of light years (one light year = 332000*60*60*24*365 or 10 kilometers)
