In the United States, wires are measured by diameter using a standard called AWG, or American Wire Gauge. Discover how the AWG system works -- and where it came from -- in this podcast from HowStuffWorks.com.

Nails are measured by a unit called a penny. This podcast from HowStuffWorks.com explains what the penny designation means -- and where it comes from.

Bullets are measured by calibers, which indicate their diameter in inches. Find out more about bullets and measurement in this podcast from HowStuffWorks.com.

(September 4, 2008) Ronald L. Dalman, MD discussions the shortcomings of monitoring AAA progression through diameter growth rates, which makes treatment of AAA disease difficult. Dalman concludes that more effective imaging during the early stages of the disease will increase therapeutic options for AAA disease. 2008 Stanford AAA Summit http://vascular.stanford.edu/news/summit.html Stanford School of Medicine http://med.stanford.edu/ Stanford Channel on YouTube: http://www.youtube.com/stanford Author: stanforduniversity Keywords: medicine human health biology clinical management bioengineering vascular surgery abdominal aortic aneurysm progression growth diameter examination screening ultrasound aorta survival risk diagnose axis vertical horizontal Added: January 26, 2009

Einstein once said that if he could understand pi then he could understand who God is. For pi is the number of God. And it truly is for. For all men were created by the Father, and all men shall return to the Father. And what is the formula for a circle? It is circumference equals pi times diameter. Diameter is the distance you are away from the Father and circumference is the path back to the Father. And how do we complete the circle? Through pi. For as the Son said, I am the narrow Gate, no one returns to the Father except through Me.

To access the complete lesson on this topic, go to www.yourteacher.com. Students learn that the circumference of a circle is the distance around the circle, and the formula for the circumference of a circle is 2 times pi times the radius of the circle. Pi is the ratio of the circumference to the radius, which is approximately 22/7 or 3.14. So a circle with a radius of 3 feet has a circumference of 2 times pi times 3, or 6 pi feet. And since pi = 3.14, 6 pi feet can also be written as 6 times 3.14, or 18.84 feet. Finally, note that the radius of a given circle is half the diameter of the circle. So to find the circumference of a circle with a given diameter, first find the radius of the circle by dividing the diameter by 2.
