In this article I will show you how to convert 643 arcseconds into radians. Throughout the explanation below I might also call it 643 arcsec to rad. They are the same thing!
How to Convert Arcseconds to Radians
A arcsecond is smaller than a radian. I know that a arcsec is smaller than a rad because of something called conversion factors.
Put very simply, a conversion factor is a number that can be used to change one set of units to another, by multiplying or dividing it. So when we need to convert 643 arcseconds into radians, we use a conversion factor to get the answer.
The conversion factor for arcsec to rad is:
Now that we know what the conversion factor is, we can easily calculate the conversion of 643 arcsec to rad by multiplying 4.848138956084E-6 by the number of arcseconds we have, which is 643.
So, the answer to the question "what is 643 arcseconds in radians?" is 0.003117353348762 rad.
