About some constants of the Earth

Is seconds amount of year Pi * 10^6 and more? 3 141 592 m and 654 mm
World's day amount per year is 365,2425 perhaps...
There are thouse sideric and synostic-years, which are not strictly and
exact that.
Do easy calculation please, and you saw that I am not lied to you.

And is the Earth-ball's radius 6283 km 185 m and 307 mm: (2*pi)*10^9.
It is also more, but why more?
Do Amercans still try to measure length's with feets?

American man's middle-lenght is perhaps same as finnishes 1,76 m I am much
shorter,
onlythat pi/2 meter = 1,57 m. I am almost findland's shortest man I think:-)
