# trig/sig figs

posted by .

There are 60" in 1', 60' in 1°, and 2π radians in 360°. Convert arc-seconds into radians. KEep 6 significant figures.

If someone could help and walk me through this process, it would be soooo appreciated!

• trig/sig figs -

1 arc-second = 1/3600 degree

so, 1 arc-second = pi/180 / 3600 = 4.8481368 * 10^-6 radians

or, 0.00000484814
