Well you can use many different tools but i would first find the radious

∙ 12y agoThe largest line of circumference on the globe is the Equator.
use a ruler to measure the length between the origin and the circumference
A circumference is just a length, it can be in meters, feet, yards, or whatever unit you use to measure or calculate it.
To find this, you'd use a cloth tape measure and measure around her.
The circumference of the earth is about 24,880 miles, so a globe with a circumference of 43 inches would have a scale of approximately 578 miles per inch.
Measure the diameter. Multiply the diameter by Pi, this will give the circumference. Pi is approximately 3.1415927 You can use the Pi symbol on a scientific calculator or use 22/7.
For one thing, they calculated (very accurately, too) the circumference of the Earth. They already knew that the Earth was a globe.
You could use a pair of calipers. Alternatively, measure its circumference using a piece of string and divide the measure by pi.
Because the circumference of a circle isn't a straight line its hard to measure, even if you have a flexi-ruler, your never going to be able to line it up to get an exact measurement. Therefore its much easier to measure the diameter and use the formula
First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide the circumference by the diameter.
You measure the girth of something by using a flexible or cloth measuring tape. Use this measuring tape to wrap around the object to measure the circumference.
You can measure the distance between two cities on a globe using a tool called a great circle distance calculator. This tool utilizes the geographical coordinates of the two cities to calculate the shortest distance along the surface of the globe, known as the great circle distance. Alternatively, you can use a string and wrap it around the globe to measure the approximate distance between the two cities.
