Convert millimeter to gigameter
Enter a value below to convert millimeter [mm] to gigameter [Gm]. Reverse conversion: Convert gigameter to millimeter.
1 mm = 1.0000e-12 Gm. To convert millimeter to gigameter, multiply the value by 1.0000e-12; to go the other way, divide by it (1 Gm = 1e+12 mm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Millimeter to Gigameter: Quick Reference
- 1 mm = 1.0000e-12 Gm
- 1 Gm = 1e+12 mm
- 10 mm = 1.0000e-11 Gm
- 100 mm = 1.0000e-10 Gm
How to Convert Millimeter to Gigameter
1 mm = 1e-12 Gm
Example: convert 15 mm to Gm:
15 mm = 15 × 1e-12 Gm = 1.5e-11 Gm

Millimeter: Definition and Use
A millimeter is a unit of length in the metric system, equal to one-thousandth of a meter.
History/Origin
The prefix "milli-" comes from the Latin word "mille," meaning thousand. The millimeter was part of the original metric system adopted in France in 1795.
Current Use
The millimeter is widely used in engineering and manufacturing for high-precision measurements. It is also a common unit in construction and for measuring small objects.
Gigameter: Definition and Use
A gigameter is a unit of length in the metric system equal to 10^9 meters.
History/Origin
The prefix "giga-" for 10^9 was adopted by the CGPM (General Conference on Weights and Measures) in 1960.
Current Use
The gigameter is used for measuring interplanetary distances, for example, the distance between Earth and Mars.
