It also depends on your tire size. What I do is check the transmission to see what gear is in it. Download a free speedometer app and go for a drive. Calculator the percentage error between the app and your speedometer and then you can calculate what gear you need to change to.

All depends on the height of your tire.

Tiresize has various features, I like the Tire Comparison, use it frequently.

A GPS with road maps and speed readout worked for me.
