Assuming a scale height of 8 km (5 mi), it's about a third of a millibar.
Less than what you get on Mars.

About 0.1 mb at 64 km (40 miles). But that probably feels like a pretty
stiff wind at 15,000 mph!



Does the effect scale up and down evenly? ie: does a 15,000 mph wind
at 0.1 mb feel just like a 1.5 mph wind at 1000 mb????
