About Gigameter (Gm)
Definition
The gigameter is a unit of length equal to 10⁹ meters, or one billion meters (one million kilometers).
Mathematical Relationship
1 Gm = 10⁹ m = 10⁶ km = 0.00668 AU.
Conversion Formula
To convert Gm to km: multiply by 1,000,000. To convert Gm to AU: divide by 149.598.
Practical Applications
Describing distances between planets in a compact metric format, though AU is preferred.
Interesting Facts
Light travels about 0.3 Gm per second (299,792 km/s ≈ 0.3 Gm/s).
Common Mistakes
Mixing up Gm with Gb (gigabyte) in mixed technical contexts. Context matters for the prefix 'giga'.
Educational Tips
The Sun is ~150 Gm away from Earth — this is a useful anchor for the gigameter scale.
