This page is for average estimates for when you make calculations that are either from a novel, lore book, etc..

## City Block

For city blocks, based on what this ^{[1]} says, there are between 16-17 per miles (2.21 to 2.50 Acres) so that would mean a city block would be 96.4x96.4 m^2.

## City

For City Size, I will be using Jacksonville, Florida as an estimate Average based on this site ^{[2]}, which the area is **1961** mi²

## Mountain

For a typical mountain. Take it as a cone with height h and steepness of 30 degrees and made of granite. The volume of a cone is V = pi*r^2*h/3 (one third base area times height). For our 30 degree mountain the radius of the base r is root 3 times h so our formula simplifies to V = pi * h^3.

Taking the height as **2000** ft we get V = 2.51 *10^10 cubic feet. A cubic foot of granite weighs about 170 lbs/ft^3, so the weight of our model mountain is about 530 * 10^12 lbs or **193.548 kg**.

Here is the link for said ^{[3]}.

## Island

For this, I will be using Paramushir for the average size of an island, which is **793 sq mi**.

I am using this site ^{[4]} as a reference.

## Country

According to the ^{[5]}, the average country size calculated from 194 world countries is **767731 sq km** (around the size of Turkey).

## Continent

According to this ^{[6]}, the average size of a continent is 17,819,000 Sq. Km (via South America)

## Moon

The average size and mass of a moon is as followed:

Size: 38 million sq km Mass: 7.34767309e+22 kg

## Habitable Planet

The average size and mass of a habitable planet based on our Earth would be:

Size: 196.9 million mi² Mass: 5.972e+24 kg

And the distance between it and the sun should be around 92.96 million mi.
