The distance from side to side through the center of the Earth is called the diameter. The Earth's diameter is 12,742 kilometers.
diameter
The circumference is the distance around the Earth at it's widest point. The diameter goes through the center of the Earth from one side to the other.
7,000 km
The distance from the surface of the Earth to its center is approximately 6,371 kilometers.
The average distance from Earth's surface at the equator its center is about 6378 km. The distance from near the north and south poles to the center is somewhat less.
The distance between the North and South Poles through the Earth's axis is approximately 12,742 kilometers (about 7,918 miles). This distance represents the Earth's diameter, as it spans directly through the planet's center along the axis of rotation.
The geometric center and the center of mass of the Earth are essentially the same point.

I'm thinking center to equator
The average height of the troposphere is 17km above the surface of the Earth.The average radius of the earth, that is the distance from its center, is 6378.1km. The two combined give a distance of 6395.1km, which would be the average distance from the top of the troposphere to the center of the Earth.
The core is in the center of the Earth.
The distance to the center of the Earth is approximately 4,000 miles.
