To convert fermis to millimeters, multiply the value by 1 × 10⁻¹². To go the other way, multiply millimeters by 1,000,000,000,000 to get fermis.
| Fermis (fm) | Millimeters (mm) |
|---|---|
| 1 fm | 1 × 10⁻¹² mm |
| 5 fm | 5 × 10⁻¹² mm |
| 10 fm | 1 × 10⁻¹¹ mm |
| 25 fm | 2.5 × 10⁻¹¹ mm |
| 50 fm | 5 × 10⁻¹¹ mm |
| 100 fm | 1 × 10⁻¹⁰ mm |
| 250 fm | 2.5 × 10⁻¹⁰ mm |
| 500 fm | 5 × 10⁻¹⁰ mm |
| 1,000 fm | 1 × 10⁻⁹ mm |
| 2,500 fm | 2.5 × 10⁻⁹ mm |
| 5,000 fm | 5 × 10⁻⁹ mm |
| 10,000 fm | 1 × 10⁻⁸ mm |
| 100,000 fm | 1 × 10⁻⁷ mm |
| 1,000,000 fm | 1 × 10⁻⁶ mm |
Fermi (fm). A fermi (femtometer) is 10⁻¹⁵ meters, roughly the size of a proton, used in nuclear physics.
Millimeter (mm). A millimeter is one thousandth of a meter, used for small measurements such as thickness and rainfall.
There are 1 × 10⁻¹² millimeters in one fermi.
Multiply the number of fermis by 1 × 10⁻¹². For example, 10 fermis equal 1 × 10⁻¹¹ millimeters.
One millimeter equals 1,000,000,000,000 fermis.
1 × 10⁻⁹ millimeters. Other common values: 100 fermis = 1 × 10⁻¹⁰ millimeters and 10,000 fermis = 1 × 10⁻⁸ millimeters.
