Convert 0.001 arcseconds to radians.

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!

 

[Doc Al]

2π radians = 360 degrees
1 degree = 60 arcminutes
1 arcminute = 60 arcseconds

 

[ZedCar]

2π radians = 360 degrees
1 degree = 60 arcminutes
1 arcminute = 60 arcseconds

That's great. Thanks very much.

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