The decameter (dam) is used to measure medium-scale distances like the length of a tennis court (~2.3 dam) or a cricket pitch (~2.0 dam). It’s also practical for land surveying and agricultural plots (e.g., a small field might be 10 dam × 20 dam). Nanometers (nm) are critical in nanotechnology, biology (DNA helix = 2 nm wide), and computing (transistors are 3–5 nm). A human hair is ~80,000 nm thick.
To convert between Decameter (dam) and Nanometer (nm), use the following formulas:
1 Decameter (dam) = 10000000000 Nanometer (nm)
1 Nanometer (nm) = 1e-10 Decameter (dam)
1 dam = 1 * 10000000000 nm = 10000000000 nm
2 dam = 2 * 10000000000 nm = 20000000000 nm
5 dam = 5 * 10000000000 nm = 50000000000 nm
10 dam = 10 * 10000000000 nm = 100000000000 nm
20 dam = 20 * 10000000000 nm = 200000000000 nm
| Decameter (dam) | Nanometer (nm) |

| 1 dam | 10000000000 nm |
| 5 dam | 50000000000 nm |
| 10 dam | 100000000000 nm |
| 20 dam | 200000000000 nm |
| 50 dam | 500000000000 nm |
| 100 dam | 1000000000000 nm |
