It is much more complicated than this, and hopefully you can see that the answer to your question is based on many variables. There are many ranches in Texas that are greater thn 50,000 acres, some as large as 250,000 acres, and a handful larger than that. A common sized ranch would be around 500 acres.
Determine how many acres you are converting to square miles. This number will probably already be given to you, but you can also use an area calculator map to determine the acreage of a real-world tract of land. For example, you might want to convert 2,500 acres to square miles. 3. Multiply the number of acres by 0.0015625{\displaystyle 0.0015625}. This decimal is a way of representing the ratio of square miles to acres, or 1640{\displaystyle {\frac {1}{640}}}, since, for every 1 square mile you have, you have 640 acres.
