The International System of Units is the modern form of the metric system. It is the only system of measurement with an official status in nearly every country in the world. ..
SI <em>SYSTEM</em><em> </em><em>WAS</em><em> </em><em>DEVELOPED</em><em> </em><em>BECAUSE</em><em> </em>
It allows people in different places and different countries to use the same units, avoid mistakes and understand each other more easily. The common base 10 of all units makes it easier and has more accurate calculations that are made without cumbersome conversion factors.....

A. The Dawes limit tells
us that the resolving power is equal to 11.6 / d, where d is the diameter of
the eye’s pupil in units of centimeters. The eye's pupil can dialate to approximately
7 mm, or 0.7 cm. So 11.6 / .7 = 16.5 arc seconds, or about a quarter arc
minute ~ 17 arc seconds<span>
Although, the standard answer for what people can really see
is about 1 arc minute.

B. It is considered as linear, so given a 10 meter telescope
(10,000 mm): </span>
10000 / 7 = 1428 times
better for the 10 meter scope ~ 1400 times better (in 2 significant figures)
<span>
<span>C. For a 7 cm interferometer, that is just similar to a 7 cm
scope. Therefore we would expect </span></span>
<span><span>11.6 / 7 = 1.65 arc seconds ~ 1.7 arc seconds</span></span>
<span><span>T</span></span>his value is what
we typically can get from a 7 cm scope.
Clues or evidence
