Astronomical scale (Moon's orbit = ~0.38 Gm). Useful for space agency data but rarely searched by the public. The Millimeter (mm) is perfect for very small measurements like the thickness of a credit card (0.76 mm), the diameter of a pencil lead (0.5-0.7 mm), or the size of small hardware components. Commonly used in engineering, jewelry design and manufacturing.
To convert between Gigameter (Gm) and Millimeter (mm), use the following formulas:
1 Gigameter (Gm) = 1000000000000 Millimeter (mm)
1 Millimeter (mm) = 1e-12 Gigameter (Gm)
0.15 Gm = 0.15 * 1000000000000 mm = 150000000000 mm
1.5 Gm = 1.5 * 1000000000000 mm = 1500000000000 mm
4 Gm = 4 * 1000000000000 mm = 4000000000000 mm
| Gigameter (Gm) | Millimeter (mm) |
|---|---|
| 0.1 Gm | 100000000000 mm |
| 1 Gm | 1000000000000 mm |
| 10 Gm | 10000000000000 mm |
| 100 Gm | 100000000000000 mm |
