Relation between dp - sp and PX

Question

I am not asking what is the difference between dp,sp and px.

I am designing a website based on google\'s new material design, all the measurements are in dp (for grid)

Answer 1

I think the answer is going to be:

1px = 1dp = 1sp on any average monitor or mobile device.

How did I come up with this?

Because a pixel is a pixel, for andriod dp and sp are used because they are used for native apps which have to scale and the dpi of each screen is different based on device. For desktops all of this is same, off course the website has to be compatible/responsive for mobile devices but since the website loads in a browser, some additional media quires (based on guidelines) will do the job.

If anybody has some other logical conclusion, please share
