about 12,000km deep.
Earth's radius is 6371 kilometers, on average. Divide that by 1.6 to convert to miles.
If you dug a hole 592 kilometers deep, you would reach the upper part of the Earth's mantle, which extends from the crust to about 2,900 kilometers beneath the surface. You would not reach the Earth's outer core, which starts at a depth of about 2,900 kilometers.
The Earth's crust varies in thickness, but on average it is about 30 kilometers (18.6 miles) deep beneath the continents and about 5-10 kilometers (3-6 miles) deep beneath the ocean floor.
The Earth's average radius is approximately 6,371 kilometers, which means its average depth is around 6,371 kilometers.
A very large batholith can extend several kilometers deep into the Earth's surface, reaching depths of 10-15 kilometers or more. Batholiths are typically comprised of intrusive igneous rocks that solidify deep within the Earth's crust.
A very massive batholith can extend several kilometers deep into the Earth's crust, typically ranging from 10 to 30 kilometers. The size and depth of a batholith are influenced by the tectonic processes that generated it and the composition of the surrounding rocks.
The border between the outer core and inner core is approximately 2,900 kilometers below the Earth's surface.
That would be the radius of the earth which is:6,378.1 kilometers
The mantle
The lithosphere of the earth is made up of the crust and the upper mantle. They are about 80 kilometers deep.
The deepest humans have traveled into the Earth is about 7.5 miles (12 kilometers) through deep mines. This achievement was in the Kola Superdeep Borehole in Russia.
It is 3963 miles to the center of the Earth, or the core.
