About Gigameters
A gigameter (Gm) is one billion meters (10⁹ m), making it useful for planetary measurements and inner solar system distances. The Sun's diameter is about 1.39 Gm, while Jupiter's diameter is roughly 0.14 Gm. The distance from Earth to the Moon is approximately 0.38 Gm. This unit bridges the gap between terrestrial measurements (megameters) and astronomical distances, providing a convenient scale for describing planetary sizes and nearby celestial distances in our solar system.
About Nautical Miles
A nautical mile (nmi) is equal to 1,852 meters or approximately 1.15078 statute miles, based on one minute of arc along Earth's meridian. This unit is the standard for maritime and aviation navigation worldwide because it directly relates to Earth's geometry, making navigation calculations simpler. Ships and aircraft measure speed in knots (nautical miles per hour). The distance between parallels of latitude is almost exactly 60 nautical miles. International maritime law uses nautical miles to define territorial waters and exclusive economic zones.
