To find how many nanometers a nickel is, we need to convert millimeters to nanometers. Here's the step-by-step process:
1. Start with the given value: 2 millimeters.
2. Convert millimeters to meters. Since there are 1,000 millimeters in a meter, we divide 2 millimeters by 1,000 to get 0.002 meters.
3. Convert meters to nanometers. There are 1 billion (1,000,000,000) nanometers in a meter, so we multiply 0.002 meters by 1 billion to get 2,000,000 nanometers.
Therefore, a nickel is approximately 2,000,000 nanometers thick.
