SUMMARY

The conversion of 0.001 arcseconds to radians is accurately calculated as 4.85 x 10^-9 radians. The conversion process utilizes the relationship where 2π radians equals 360 degrees, with 1 degree comprising 60 arcminutes and each arcminute containing 60 arcseconds. The correct formula applied is (2π / (360 x 60 x 60)) x 0.001, which yields the precise result. Miscalculations can occur if the calculator is not set to the correct mode or if the conversion factors are misapplied.

Homework Statement



Convert 0.001 arcseconds to radians.

I believe the correct solution is 4.85 x 10^-9 radians.

Homework Equations



2∏rad = 360° = 60' = 3600''

The Attempt at a Solution



The way I was trying to achieve this solution is by setting my calculator to radian mode, typing in {2Pi/(60x60)} x 0.001 which gives 1.74x10^-6.

So I was wondering what I'm doing wrong?

Thank you!
 
Physics news on Phys.org
2π radians = 360 degrees
1 degree = 60 arcminutes
1 arcminute = 60 arcseconds

1 arcminute = 60 arcseconds

That's great. Thanks very much.

(2∏ / (360x60x60)) x 0.001 = 4.85x10^-9
