The hectometer (hm) is useful for measuring sports tracks (1 lap = 4 hm), urban blocks (~1–2 hm long), or vineyard rows. Road signs in some European countries use hectometers for minor distance markers. Picometers (pm) describe atomic radii and X-ray wavelengths. A hydrogen atom is ~53 pm wide. Used in crystallography and semiconductor engineering.
To convert between Hectometer (hm) and Picometer (pm), use the following formulas:
1 Hectometer (hm) = 100000000000000 Picometer (pm)
1 Picometer (pm) = 1e-14 Hectometer (hm)
1 hm = 1 * 100000000000000 pm = 100000000000000 pm
2 hm = 2 * 100000000000000 pm = 200000000000000 pm
5 hm = 5 * 100000000000000 pm = 500000000000000 pm
10 hm = 10 * 100000000000000 pm = 1000000000000000 pm
| Hectometer (hm) | Picometer (pm) |

| 1 hm | 100000000000000 pm |
| 2 hm | 200000000000000 pm |
| 5 hm | 500000000000000 pm |
| 10 hm | 1000000000000000 pm |
| 20 hm | 2000000000000000 pm |
| 50 hm | 5000000000000000 pm |
