The Nautical Mile is used for global navigation, equaling one minute of latitude (about 1.15 statute miles). Commercial airliners cruise at altitudes of 35,000-40,000 feet (about 6 nautical miles). Modern nautical charts still use this measurement, and international maritime law specifies territorial waters in nautical miles. Astronomical scale (Moon's orbit = ~0.38 Gm). Useful for space agency data but rarely searched by the public.
To convert between Nautical Mile (nmi) and Gigameter (Gm), use the following formulas:
1 Nautical Mile (nmi) = 0.000001852 Gigameter (Gm)
1 Gigameter (Gm) = 539956.8034557236 Nautical Mile (nmi)
1 nmi = 1 * 0.000001852 Gm = 0.000001852 Gm
5 nmi = 5 * 0.000001852 Gm = 0.00000926 Gm
10 nmi = 10 * 0.000001852 Gm = 0.00001852 Gm
20 nmi = 20 * 0.000001852 Gm = 0.00003704 Gm
50 nmi = 50 * 0.000001852 Gm = 0.0000926 Gm
100 nmi = 100 * 0.000001852 Gm = 0.0001852 Gm
