Step-by-Step Solution
To convert 4 arc seconds to radians, we divide by 206264.71 because one radian equals exactly 206264.71 arc seconds.
1 radian = 206264.71 arc seconds
Since there are 206264.71 arc seconds in every radian, we divide our value by this factor:
4 ÷ 206264.71 = 1.9393e-5 radians
So 4 arc seconds = 1.9393e-5 radians.
Quick check: 1.9393e-5 × 206264.71 = 4 arc seconds
