Astronomical scale (Moon's orbit = ~0.38 Gm). Useful for space agency data but rarely searched by the public. 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 Gigameter (Gm) and Picometer (pm), use the following formulas:
1 Gigameter (Gm) = 1e+21 Picometer (pm)
1 Picometer (pm) = 1e-21 Gigameter (Gm)
0.15 Gm = 0.15 * 1e+21 pm = 150000000000000000000 pm
1.5 Gm = 1.5 * 1e+21 pm = 1.5e+21 pm
4 Gm = 4 * 1e+21 pm = 4e+21 pm
| Gigameter (Gm) | Picometer (pm) |
|---|---|
| 0.1 Gm | 100000000000000000000 pm |
| 1 Gm | 1e+21 pm |
| 10 Gm | 1e+22 pm |
| 100 Gm | 1e+23 pm |
