8 Inches Per Mile Squared Chart

Accuracy looks to be within 1 inch until about 22 or 23 miles. The 8 inches per mile squared is actually correct for up to around 100 miles.

Earth Curvature Refraction Experiments Debunking Flat Concave

8 inches per mile squared chart. One thing you hear flat earthers say often is that the curvature of the earth is 8 inch per mile squared. And therefore the rule is unsuitable to determine the amount of obstruction of a distant object due to earth s curvature. Eight inches per mile squared never curves back on itself and becomes progressively less circular as the distance increases.

Where does it come from. If you draw a large circle and a straight edge extending straight out from the top of the circle you will see that each incremental measuring unit along the straight edge correlates with a longer drop than did the previous unit. The square of 12 500 is 156 250 000 and 156 250 000 times 8 inches is 1 250 000 000 inches or 236 742 miles.

Thank you all for watching. 8 inches per mile squared. About the distance to the moon.

A truncated taylor series expansion for sqrt r 2 d 2 r. How many times have you heard that phrase now. The eight inches per mile squared is a rule of thumb to determine the drop height due to the curvature of the earth.

The distance to the horizon in miles from height of an observer is approximately equal to 1 23 times the square root of the height in feet. It does not account for the observer s height and atmospheric refraction. The 8 inch per mile square is such a failure.

The earth has a radius of approximately 3965 miles. Using the pythagorean theorem that calculates to an average curvature of 7 98 inches per mile or approximately 8 inches per mile squared. This is only a rough estimate for the first few miles though.

It is way better to use the. Dividing by 7920 is a pain so let s convert miles to inches. Click in the graph above to get all values for a certain point.

I mean suddenly that 0 2 make it totally logical for object to not be hidden by the curve of the earth when they mathematically should be by the pathetic 8 inch per mile squared bs. At 1 mi or 1 609 km its error is about 0 0314 and decreases to 0 at 391 1 km or 243 1 mi. 0 2 of failure i guess that means the whole flat earth theory as been rendered useless by that 0 2.

The 8 inches per miles squared approximation function underestimates the correct value at distances less than 391 1 km or 243 1 mi so at 391 1 km it is the most accurate. See what i mean. H d 2 5280 12 7920 5280 12 7920 8 so there it is.
