Visualizing huge numbers can be very difficult. People regularly talk about millions of miles, billions of bytes, or trillions of dollars, yet it's still hard to grasp just how much a "billion" really is. The MegaPenny Project aims to help by taking one small everyday item, the U.S. penny, and building on that to answer the question: "What would a billion (or a trillion) pennies look like?"

All the following pages have tables at the bottom, listing things such as the value of the pennies, size of the pile, weight, and area (if laid flat). All weights and measurements are U.S. standards, not metric.

It's best to step through the project from beginning to end, but if you'd like to just jump in, links are available below.
