- Meter: a unit of length equal to 100 centimeters or 39.37 inches. A meter is also about the same length as a yard.
- Millimeter: a unit of length that is one thousandth the size of a meter, and one tenth size of a centimeter.
- Simulate: to look like, take the shape of, or sound like something else; imitate.
Now that we know how large a one inch line becomes when we magnify it one hundred thousand times (100,000 X), what would happen if we magnify the same line a billion times (1,000,000,000 X)?
| Continent | Area (miles²) | Area (kilometers²) |
| Africa | 11,725,922 | 30,370,000 |
| Australia | 2,934,376 | 7,600,000 |
| Europe | 3,930,520 | 10,180,000 |
| North America | 9,455,642 | 24,490,000 |
| South America | 6,888,062 | 17,840,000 |
Here is an activity for you.
If you have followed the two mathematic activities it becomes clear that changing the size of things can have a very big impact. However, the biggest impact is still to be calculated. If the nano world is actually one billion times smaller than a meter, to get an idea of the reverse you need to calculate the size of a one meter line magnified one billion times.
Take a line one meter long by one millimeter wide and calculate the magnified size if we magnify it one billion times and answer these questions.
How many times could the line go back a forth between the Earth and the Moon?
How many Earths could you cover with the magnified line if were carpet?
