In game to IRL height conversions (6100m IRL)

[Jovis]

So I've just made an F4U Corsair, and managed to take it to roughly the top speed I could find on the internet by diving, but the wiki says it reached roughly 200m/s at 6100m. I know that Kerbin is, however, smaller, so 6100m would be lower, so my question is:

What altitude would i have to reach in ksp to be at the equivalent of 6100m in real life?

Thanks for any and all help.

Kerbins atmosphere is 70% Earths so 4270m

Kerbin is actually smaller than that.

 

Kerbins atmosphere is a little over 1/3rd the size of Earths. 

 

Earths atmosphere tops out around 180km.   Kerbin is 69km. 

 

So 6.1km asl, is closer to 18km ASL real life.  As far as I know, no F4U flew above 40kft or 12km.

Atmospheres in KSP are cropped absolutely at a fairly arbitrary value. above the cutoff nothing is modeled

The 70km cutoff at Kebin corresponds to 100km at Earth.  Everything below is modeled on a 70% scale of the US standard atmospheric model

After mixed answers, I'm going to go with about 70% of real atmosphere being kerbin. Thanks for all the help, and I think it's time I re-researched the plane, as the site I was reading from was complete krakens.

It's an 80% scale, not 70%.  The temperature, pressure and density that is present at the real life altitude of 6100 m occurs at an altitude of 4880 m on Kerbin.

Kerbin's atmosphere is based on the U.S. Standard Atmosphere, with the height multiplied by a factor of 0.8.

No it doesn't.  The top of Kerbin's atmosphere is based on the 86 km height of the USSA factored by 0.8, which works out to 86*0.8 = 68.8 km.  It was then extrapolated out to 70 km just to make it a nice round number.
