How to convert millimeters to gigameters

1 millimeter is equal to 1 × 10⁻¹² gigameters, and 1 gigameter is equal to 1,000,000,000,000 millimeters. To convert, multiply by the conversion factor:

gigameters = millimeters × 1 × 10⁻¹²
gigameters = millimeters ÷ 1,000,000,000,000

Example: convert 1 mm to Gm: 1 × 1 × 10⁻¹² = 1 × 10⁻¹² Gm.
