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. 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 Hectometer (hm) and Nanometer (nm), use the following formulas:
1 Hectometer (hm) = 100000000000 Nanometer (nm)
1 Nanometer (nm) = 1.0000000000000001e-11 Hectometer (hm)
1 hm = 1 * 100000000000 nm = 100000000000 nm
2 hm = 2 * 100000000000 nm = 200000000000 nm
5 hm = 5 * 100000000000 nm = 500000000000 nm
10 hm = 10 * 100000000000 nm = 1000000000000 nm
| Hectometer (hm) | Nanometer (nm) |
|---|---|
| 1 hm | 100000000000 nm |
| 2 hm | 200000000000 nm |
| 5 hm | 500000000000 nm |
| 10 hm | 1000000000000 nm |
| 20 hm | 2000000000000 nm |
| 50 hm | 5000000000000 nm |
