What is wrong here??

I'm teaching myself celestial navigation and I wanted to double check my results on google earth. The calaculated and assumed distance was out by a factor of 2. I wanted to double check how Google Earth measures distances and inputed two points, 0 0.0n, 0 0.0w and 0 0.0n, 0 1.0w. That is 1' of arc and that should equal 1nm should it not? When I measure between these 2 points I do not get that answer. Why not?
