Astronomical scale (Moon's orbit = ~0.38 Gm). Useful for space agency data but rarely searched by the public. 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.
To convert between Gigameter (Gm) and Nautical Mile (nmi), use the following formulas:
1 Gigameter (Gm) = 539956.8034557236 Nautical Mile (nmi)
1 Nautical Mile (nmi) = 0.000001852 Gigameter (Gm)
0.15 Gm = 0.15 * 539956.8034557236 nmi = 80993.52051835853 nmi
1.5 Gm = 1.5 * 539956.8034557236 nmi = 809935.2051835854 nmi
4 Gm = 4 * 539956.8034557236 nmi = 2159827.2138228943 nmi
