How to adjust the difference between the coordinate from openstreetMap and google map

Question

I have downloaded the OSM from OpenstreeMap that came with all nodes from the map and their respective coordinates. Now I have to plot a node (latitude and longitude) on Google Map, but all coordinates goes in different places than it should be.

To illustrate I got the node -12.92122,-38.34991 (lat,long) on google maps and openStreetMap as you can see on screenshots.

My question is how can I adjust these values.. so I can plot the node on google maps at the same place of openStreetMap.
