Noise equation

I was looking at the noise equation listed in this link:


where it says Noise = Noise Density * sqrt(BW * 1.6)


where BW is the accelerometer bandwidth, set by capacitors on the accelerometer outputs.


Suppose I use the spec for the ADIS16130 shown here.


Given a BW of 0.08KHz and density of 0.015 deg/sec/rtHz. Following that equation,  I get a noise of


0.015*SQRT(0.08*1000*1.6) = 0.16971 deg/sec,


Somehow that noise number looks kinda high and incorrect to me.


What is that I missed?
